Why does my girlfriend not consider my feelings?

[Anonymous]

I love this girl. But I have a problem. When I am angry I get manipulative. And I am trying my best to catch myself whenever it happens. I have hurt this girl in the past. And I feel I am not worth it. She says I am. And I take into the consideration that we don't like each other talking to people of the opposite gender. for fear of the other being stolen. But she doesn't consider how I feel. I am OK with her talking with other men. But she is a oncoming freshman. and she has a friend who says she is his. yes his adoptive freshman. I have been hurt many times in the past and I find a huge fear in that. And I have asked her to please not be his whatever. But she won't and I got manipulative and I couldn't realize it and we are fighting. I realize what I did was wrong. But she never considers my feelings that's what I feel. And when I am even talking to my friends I take into consideration about how she would feel. But I don't think she does with me. And I am a terrified Boy. What do I do? does anyone have any suggestions?... Because she says she does take consideration for me when talking.. But this whole adoptive freshman thing just bugs me to death...

Break up. You need to resolve your manipulation and insecurity issues before you date again. Plus, you should never stay in a relationship with someone you can't trust (or someone you think doesn't care about your feelings). End it.
