Sounds like a bad situation to me. If she is really like that when she is about to start her period, then she should seek medical attention. Usually birth control pills really help with the hormone issues. One thing that I think you should consider is how will you handle her moodiness later on down the road? If she is this bad now, just imagine how moody she will be with a job to keep and bills to pay. The time right after high school or college when you have to really go in the real world and you are on your own is the most stressful, at least it was for me.

My SO is divorced. His ex-wife was very much like the woman you are describing, only worse. She would feign mirgranes so he wouldn't go out with his friends. The reason we know she was faking was that as soon as he said he would stay home to take care of her, she would magically feel better and want to go out, just the two of them. She did have real migraines though, so she wasn't always faking. She was very moody and manipulative. He only realized later that the main reason he married her was he felt she needed him, and he wanted to be needed. They were also high school sweethearts.

I don't much about your situation but it sounded eerily famliar to me. I would just be very careful in this relationship if I were you. And if you can't stand her moodiness then maybe you two aren't as compatable as you once thought. After all, if she has always been moody you will either have to get used to it or move on. Most people don't change that much. You can't depend on change, that's for certain.

Just my two cents. YMMV
