I tell my kids all the time that when people show you who they are, you should believe them.

This is very good advice, which I am considerably better at giving than following.

I think that is because it is easier to see somebody clearly when you do not love them. When you do, there is history standing between you and whatever they are doing right now. There are old jokes, long conversations, grocery store trips, cigarettes smoked together, kids raised alongside each other and stupid little memories nobody else would understand. There are versions of that person stored in your head who showed up for you, made you laugh and knew things about your life that newer people never will.

Love covers a multitude of sins, as the saying goes. Sometimes it also makes us very generous in our interpretation of warning signs. Not because we are stupid or because we cannot see what is happening, but because we keep allowing for the possibility that the person we knew is still in there somewhere.

One of the hardest relationships for me to accept changing was with one of the first truly close female friends I ever had. We were friends for years before our lives became tangled together in other ways. She lived with me while I was pregnant with my daughter, back when we were all crammed into a little efficiency apartment and somehow trying to go to school while still living a life that was much messier than anything our homework assignments suggested.

I remember sitting on my bed one night with my laptop while she worked from a cot across the room. I had barely eaten all day because almost everything I tried came right back up.

“You haven’t eaten all day,” she said.

I told her I did not feel like eating. There was not much point if I was just going to throw it up anyway.

So she went into the little kitchen and baked one of those pepperoni Tombstone pizzas, one of the only things I could reliably keep down while I was pregnant. Then we sat there on opposite sides of that tiny room, both doing homework on our laptops, eating frozen pizza and drinking Mountain Dew while somehow also still living this completely chaotic hustling life around all of it.

That is the version of friendship I remember. Not big declarations. Somebody noticing I had not eaten and putting a pizza in the oven.

We raised kids alongside each other. We ran errands together. Going to Walmart counted as hanging out. For a long time, I knew the rhythm of her life and she knew mine.

Then things changed.

There were years when the relationship was rocky, followed by a few when I thought I had gotten some of my friend back. Not exactly the friendship we had when we were younger, because neither of us was that person anymore, but something familiar enough that I thought maybe we had made it through.

Then everything shifted again.

What surprised me this time was that I did not feel much anger. Mostly I felt tired. The relationship was adding stress to my life and creating strain in another relationship that mattered deeply to me. I found myself wondering how much energy I wanted to keep spending trying to preserve something simply because it had once been important.

That sounds colder written down than it felt. I was not asking what she could do for me. Friendship is not supposed to work that way. I was asking something more basic.

Is this relationship still something good in my life, or am I holding onto it because it used to be?

History matters. I just do not think it gets the final vote.

I have had to answer that question more than once, and not always for the same reason. Sometimes someone changed so much that I could no longer find the person I loved inside the relationship. Sometimes they stayed almost exactly where they had always been and I was the one who moved. Sometimes there was no dramatic betrayal at all. Our lives simply stopped fitting together.

One friend I loved very much was enormously important to me when my daughter was little. She helped me tremendously. We had good times together, and there is a version of her I will probably always be grateful for.

Then alcohol and drugs changed her.

Maybe they changed her. Maybe they magnified things already there. I do not know, and at this point I do not need to know. Eventually I realized I was trying to maintain a friendship with the person I remembered rather than the person standing in front of me.

I was chasing a ghost.

That was harder to admit than simply being angry with her would have been, because the ghost was real once. The memories were real. The help she gave me was real. The love was real.

None of that made the present version of the relationship healthy.

Good memories can carry a relationship a long way. I just do not think they can carry it forever.

Other relationships ended for almost the opposite reason. The person did not change much. I did.

There is a man I still think about sometimes when I drive near his mother’s house. There is a particular gas station that makes me think of him because it is where I saw him for the last time.

He belonged to a very different version of my life. Back then, there were rules about loyalty that made perfect sense inside the culture we were living in. He broke one of those rules when he talked to the police and gave up one of our friends, and that was the end of us.

I do not live by those rules anymore.

I can look back now and understand that a lot of what we called loyalty was wrapped up in a life I would never choose again. Still, I miss him sometimes.

I miss other people from those years too. I miss laughing until my stomach hurt. I miss the stories. I miss the sense that everybody knew everybody and that wherever we were going, something was probably going to happen.

Sometimes I even miss the feeling of recklessness.

I do not miss being reckless.

Those are not the same thing.

Memory is funny that way. It can hand you back the adrenaline without immediately handing you the consequences. You remember driving around all night and everybody laughing, but not always how often you had no idea how the night was going to end. You remember feeling fearless and forget that sometimes you were simply unsafe.

There are people I miss from that life who are still living almost exactly the same way now. I do not hate them. I do not think I am better than them. I just cannot go back there in order to keep them.

Sometimes somebody changes so much that you barely recognize them. Sometimes they stay almost exactly the same and you are the one who moved on. Sometimes both people change and discover that whatever once held them together belonged to a particular season.

There does not always have to be a villain, and there does not always have to be reconciliation.

I tend to leave doors open. There are people I have loved so deeply that shutting one completely feels unnatural to me. One relationship in particular will probably always have a door somewhere because I once loved that person like a daughter. We see the world very differently now. She has beliefs about my marriage, my life and the way I choose to live that make closeness between us difficult.

Maybe someday those beliefs will change. Maybe they will not. I cannot do that work for her.

What I can do is stop sitting beside the door.

I can leave room for somebody to come back without chasing after them. I can love someone and still decide that I am not going to keep explaining myself. I can acknowledge that a relationship mattered without insisting that because it mattered once, it has to exist forever.

Because eventually there is a point where continuing to go after someone who keeps showing you they cannot meet you there is just you hurting your own feelings.

I have done that more times than I would like to admit. I have made excuses because I loved the person, and sometimes I did not even form the excuse into a complete thought. History did the work for me.

She has been there for me before.

He was important to me.

We have known each other forever.

She is going through something.

Maybe this will blow over.

Sometimes those things are true. Sometimes love should make room for somebody to have a bad season, and that is what makes the line so difficult to find.

I do not want to become a person who discards everyone the minute a relationship becomes inconvenient. People are complicated. I am complicated. I have needed grace in my own life, and I want to give it.

But grace does not require me to keep volunteering for the same hurt.

At some point I have to pay attention to what is actually happening instead of continually voting for the person I remember.

Sometimes a boundary is dramatic. More often, at least for me, it is incredibly ordinary. You do not send the message. You do not find a reason to check in. You do not restart the same conversation hoping that this time you will finally find the exact sentence that makes somebody understand.

You drive past the house. You pass the gas station. You remember the grocery store trips and the little efficiency apartment and a Tombstone pizza in the oven. You hear something funny and know exactly who would have laughed at it.

And you keep driving.

I think I used to believe that if I still missed someone, there must be unfinished business there. I do not believe that anymore.

Some relationships in my life are completely finished. Others may not be. I do not know what the future holds with every person I have loved, and I do not need to decide all of that today.

What I know is that missing someone is not the same thing as being called back to them.

Sometimes you miss somebody because they mattered. Sometimes you miss who they were. Sometimes you miss who you were when you knew them. Sometimes you just miss a Tuesday afternoon twenty years ago when everybody was still getting along and nobody knew yet what was coming.

None of that means you are supposed to go back.

There are people I will probably miss for the rest of my life. That does not mean I made the wrong decision by letting them go.

It means there was something worth missing.

And sometimes that has to be enough.
