I know I'm not the only dude that has gone through this. You and your girl are cool right? Everything seems picture perfect, then out of the clear blue she either:

a) Starts acting really really depressed for no apparent reason
b) Gets really really mad at you over small things
c) Says she wants to break up with you over said small thing, then 3-5 days later says she wants to get back together.

If you notice this pattern in your girl I've chalked it up to two different things:

1) She's bi-polar
2) PMS

More than likely it's number two, hehe. Now I'm not sexist by any means, and call me crazy but I think it's adorable now how my girl will break up with me whenever it's that time and then like a few days later say she didn't mean it. I've actually grown accustomed to it and have literally marked off the calendar for potential "break up days." I know you probably think it's insane because how would I ever know if she were serious. Simple...if she starts late on her "break up days." Plus, once you've been with someone long enough, you know how they really feel despite their rapidly flowing emotions. haha.

Comments, opinions? heh.

I experience PMS, but I usually don't take it out on my partner, and I definitely don't threaten to break up with him. The only times I've wanted to break up with a partner during PMS it was because I'd been thinking about it for a while, and all those hormones brought it to the surface so I couldn't deny it any more.

I think you need to have a talk with your gf and see if she's serious about wanting to break up. If she is, you have some talking to do. If she isn't, she needs to drop the subject -- PMS or not. Hormones *do* influence us, but we still have some control!

I think it is number 2. But it could also be that the girl is a 'drama' queen. Drama queens need to make a scene every once in a while to get something out of their system. Maybe it's because of something she had to live with when she was younger, I don't know. But yes, you are NOT alone.
