Is it normal to be really angry at an ex?
Angry to where you want to beat them up.
Long story short I had an ex boyfriend who harassed me online. We were together for 2 years and when we broke up he kept saying mean things in hopes that i will get back with him. I had to inform the police to get him to stop. I've been upset because he was the only friend I made in high school and had I known he was that kind of guy I wouldn't have been with him.
Ive also had nightmares where I would yell "get away from me!" to him.
