<human>: Summarize the given text in a few sentences.

Common story: he gave up on the relationship but didn't tell me until a few months later... he didn't have the guts to break up with me, so I broke it off when I found out he had cheated. Since then we've messaged a couple times and I pieced together that he stopped caring about me a long time ago.

End of story, right? No loose ends, no mixed messages. Except I still don't feel any better. I can't stop having imaginary conversations with him in my head. Sometimes I get angry thinking about how he treated me, and want to tell him what a fucking coward he is for not being honest. Other times I remember what it was like when we first met, how amazing our chemistry was, and I want to tell him I'll always love him even though he fucked up.

But telling him anything is just going to prolong the heartache. There's nothing I can say that would make him love me again. All these thoughts in my head are pointless, yet they won't stop. I haven't had a good night's sleep in weeks because as soon as my daily distractions are gone, the suppressed emotions come back.

The truth is I'm afraid to let go. Not because I'm afraid of being alone again, but because admitting there's no future for us means admitting that I was wrong. 

I was wrong about you being the person I was going to spend the rest of my life with. Wrong that I could be everything you wanted, wrong that working through the hard times would be worth it in the end. I was wrong when I thought I could be friends with someone I love. And I was wrong when I thought you loved me as much as I love you.
<bot>: Afraid to let go. I miss him. He's an asshole. It wasn't real. Feelings suck.
