obviousley this guy is too ignorant to know what he's got, lose him.
"he says i'm just being a typical jealous bitch." -- that's outta line for a start,
he would never call u a bitch if he thought anything of u, and if he had any respect for u and your feelings he would at least watch his porn in private (or not at all) and
i gotta admit, i love porn, but i would feel uncomfortable watching it with a woman anyways.
"When I feel this way and start thinking about all the negative things in my life. I start to think I'm worthless" -- don't let that asshole make u feel that way, were u this depressed before u met the guy ??
Do yourself a favor and find yourself a man who knows how to treat u right.
