I have to weigh on this because I was in a situation with a VERY jealous and controlling woman. Now - she didn't try to physically harm me - but the progession to crazy was slow and I didn't realize what was happening until it was really bad. There were small signs - that I notice in retrospect - but at the time I was clueless. It was weird, but one day, I turn around and realize that this chick was fucking insane. I just say this because sometimes, you don't even know what's happening until something really big happens.
