Yeah, I do - but the sadness is giving way to anger.
Initially when I left, I felt really guilty, like I was abandoning him. He was very manipulative and made me feel like I was responsible for his life as well as my own. I got over that, and then I felt really stupid for ever choosing to be with a person who would treat me that way - again, blaming myself, but this time for making "poor choices."
Now when I think about it, it just makes me really angry, more at him than at myself. I don't have any contact with him (although I heard from a friend that he tried to find me last year, which was creepy), but just knowing he's out there... I don't know, I just don't think he deserves to exist.
My feelings sound more dramatic in writing than they actually are.
Most of the time, I'm really happy. I've been in a wonderful relationship for the past two years, with a man who truly loves and respects me. But I'm still really angry (both at my ex and myself), and I'm trying to work through that.
If you ever want to chat, feel free to PM me! I know how lonely it can be to go through something like this, even when you're surrounded by supportive people, and even though you recognize how much better off you are now.
That was kind of a long answer - sorry!
