Resentmen
I woke up this morning feeling angry with my ex-husband, whom I've been divorced from for 2 years. I was thinking about things I felt hurt about in our relationship. He used to be controlling and jealous. We've been divorced for over 2 years. He is growing up and acting like a more respectful person and now I suddenly have so much resentment toward him for not having been that man when I was with him. I never want to be back with him, so there's really nothing for me to do but get over it. I thought I would be over it by now.
Yes, get over it. Good for him for learning from his experience with you.
