My girlfriend takes all her stress and anger out on me!

She has severe anger issues that are stemming from behavioral patterns she learned as a child. She learned a long time ago that she can get her way and maintain a sense of control through force, aggression, temper tantrums, and physical violence. Only she can change the way she deals with the world, and it is going to be difficult for her to do so, and sadly I don't think there is much chance she is ever going to treat you differently.

The most important thing is that you realize you don't deserve this kind of treatment and her behavior actually has very little to do with you. She wants to be in control of everything and everyone around her, and she hates the feeling of helplessness she feels when she realizes it is impossible to do so. So she turns to the things she feel she CAN control- namely, you. She is mentally and physically abusive and I strongly urge you to leave her. Not only will you save yourself all the hurt and insanity that comes with a unhealthy relationship, but she may just learn a valuable lesson about how to treat people properly.

Besides leaving her, you need to use this experience to figure out what kind of girl you want (note: not what kind of girl you don't want, there is a difference).

It also tells you what constitute an abusive relationship. From what you wrote, it appears that she did most, if not all, of what abusers do to their partners.

Putting you down
Making you feel bad about yourself
Calling you names
Implying that you are crazy
Playing mind games
Using guilt as a weapon of control
Using humiliation
Making light of the abuse
Saying abusive behavior was not abusive
Shifting the responsibility for the behavior to you

I hate to be the first post to say the obvious but...

There is only a slight chance that someone like this is ever going to change from the 'blame anyone else' mode as this is a function of her lack of self discipline and absense of personal responsibility. Responsible adults see two or more sides to each story and do not hit others. Ever. You seem rational in your post and while I'm only hearing your side of the story I have personally known another girl with behavior issues similar to those you describe and she eventually lost all but the most tolerant of friends due to her abusive behavior. You might want to consider how long you want to withstand this continued poor behavior because it's unlikely to change.

And BTW all guys are pervs, some more openly but all check out a nice rack if it's placed on display.
