Hey Artie hon,
I just wanted to say I’m so sorry for how selfish I was when we were together, both times being completely honest. I was so worried about myself and my life that I didn’t see when you were struggling. That was really hurtful and toxic of me. Now I’m gonna be honest. I miss us, I miss the good and the bad but I will never make or would I ever want you to go through all the pain that I put you through ever again. I hope you are much happier now, I love you and I hope you can accept my apology. (Very formal I know but I wanted a good apology)
