<human>: Provide a brief overview of the text.

Both of us are 28 and we have been together for a bit more than a year  (I am the boy).  I really love my girlfriend a lot.  She has a lot of very good qualities and in many ways this is a very good fit.

The only thing is that her extreme emotions and temper really bother me.  She never gets violent and she usually has some reason, but the way she reacts to things is ridiculous.  For example (one not involving me)... her best friend with whom she lives asked us to take care of our dishes.  It was a little annoying of her because we had just left them there for like an hour and we never leave dishes about.  My girlfriend refused to talk to her friend (like flat out giving her the cold shoulder) for almost a week just because of this.  She even got mad at me for talking to her friend.   

This is the problem.  A small thing turns into something enormous and she is basically mad at me every single day.  This really is not an overstatement, it is almost every day.  She will hang on to the most innocuous thing that wouldn't even register with many people. She usually accuses me of not loving her (which makes me furious) and sometimes will ignore me.  And almost all of the time it is over mind numbingly small stuff (of course there are times I deserve a little bit of anger).  These emotions are usually caused by feeling disrespected or if she doesn't get her way about something.

She acknowledges she has this problem and just says she can't help that she is so emotional.  I have tried telling her how much this upsets me repeatedly.  Everytime it has ended with her accusing me of not loving her and she will just say why are you even with me?  Nobody is forcing you!

I just need advice on what I can do to make this behavior change.  I don't care if she is like that to others, I just don't like that she is like that to me.  Has anybody had a success dealing with something similar in the past?  For the record, she is a very sweet person a lot of the time and I don't want to end the relationship.
<bot>: Girlfriend has a bit of a temper.  I don't know how to talk to her about it without her getting angry.
