Search Results: earning trust

So I've been in a relationship with a girl for just over three years now. It's mostly great, however she has one flaw that I'm not entirely sure I can live with.

Each month her mood goes crazy. Now don't get me wrong, I wouldn't mind at all if she just got upset, or needed cheering up or hugs etc, the issue I have is that she starts massive arguments over absolutely nothing. However that's not the worst, the worst is that if I happen to have something go wrong in my life at the time of her mood swings, then I get attacked (sometimes literally, I have a permanent scar on my arm from her).

Example: We were watching a film and I start to very suddenly feel pretty nauseous. So I run into the bathroom, and just hang there for about 10 minutes spitting out the excess saliva and trying not to throw up. She doesn't come to see if I'm ok (which is fine). Then I go back into the room and she is on her phone. I stand there groggily and croak, "Uhhhgg I feel really ill" and she turns to me and says "I figured..." then goes back to her phone. I frown and say that that wasn't very nice and she goes balistic, starts shouting at me for daring to talk to her like that etc.

Another Example: She kissed another guy and told me (after realising I was going to find out anyway). We have a discussion and I ask her if she still wants to be with me, she says yes etc and it was good enough for me. So I forgive her, saying that she's going to have to earn back my trust. Over the next few days she's moody again and snaps at me, and ignores me. I'm sitting there thinking wtf? So I call her up on it and she flips out again, shouting at me and saying she's not sure anymore, she's confused. I tell her to just leave the flat and come back when she figures it out. She comes back a week later and is massively apologetic and saying she hopes she hasn't ruined anything and she'll do anything etc. So against my better judgement I give her another chance.
