You....person
Dear J,
I don't know what happened that made you make the decisions you chose, but I'm so disappointed that you made those decisions. In a way I wish that you had been happy and that you cared enough about me to want to stay with me, and only me, for the rest of your life. But you didn't, and I see that now. I see that you had something with her but you were getting bored so you tried to walk down two different roads at the same time. So instead of giving her her life, you kept hers and stole mine and the other people you were with.
I'm sorry for judging you even though you hurt me. And I'm sorry that you felt you needed her more than me. I guess this is goodbye for the last time.
