I messed up big time, Mark

Okay, so, Mark, if you ever see this, I need to say it. I'm sorry. I'm so, so sorry for what I did at Sarah's party. You were out of town, and I was feeling...lonely, I guess? That's not an excuse. It was stupid and selfish. I got drunk, and I kissed David. David, your *best friend*.

I know, I know. It's awful. I didn't mean for it to happen, but that doesn't change anything. I should have stopped it. I should have walked away. But I didn't.

We're not together anymore. You found out, obviously. It broke your heart, and you had every right to be furious. I destroyed the best thing that ever happened to me. I replay that night in my head a thousand times, wishing I could take it back. I don't expect you to forgive me. I don't even deserve it. But I needed to say it. To put it out there. I hope you're doing okay. I really do. You deserve to be happy, Mark. Even if it's not with me. Maybe, someday, you can understand that I never wanted to hurt you and that I really did care about you. Now, it's just a matter of hoping that you can heal from my stupidity. I just wanted to confess and wish you the best.
