Keep trying? or is this time for an end? Please Help.?

My girlfriend and I have been dating for about half a year now, and we have fallen in love with each other. The problem is that she has a lot of issues with trust, and she has the biggest anger problem ever. She seriously just explodes and throws tantrums. She says and does things that she will regret doing. She takes everything so serious and takes things out of proportion. I have tried so hard to keep things together but I don't know how much more of this I can handle. I've told her, "you have to stop all of this." Yesterday, I left 5 minutes early to class, she called yelling at me saying "you must have left early to talk to girls in the class" She also cussed me out in a class that we have together after I showed her how to draw something then sarcastically said that "you copied my idea" as a joke. We went home to her apartment and gave me an attitude and yelled some more. I broke it off with her and I can't stop thinking about giving her another chance. What should I do?

Just some more background to our relationship. I we have broken up so many times, but I always find myself coming back to her or calling her. I know she loves me and I love her as well. I told her the other day, "if you keep doing this, I am going to have to end it." I know she has a lot of problems and I want to help her with them. We have gotten a lot better because we used to fight almost every other day. It is just so irritating when she does this, especially when she gets angry. She says and does some crazy things. I love her like crazy, what should I do. Thanks for all who is looking at my question and trying to help out with my life, thanks again.

wow if she is going to treat you like that then stay away from her! she has serious issues that need help and until she is getting help i would steer clear of her. As much as it may hurt, you don't deserve to be treated like that. :(

Keep her in your thoughts ,but she needs time to grow up and mature, don't be so serious, you guys have a lifetime to be together.

If you want to give her another chance, I'd recommend she has anger management or at least sees someone about her anger/jealousy issue because it doesn't sound rational (unless she has a reason to mistrust you). I'd try and have a calm talk with her about how she is making you feel when she acts this way, if she cares about you and your relationship hopefully she will work on it.
