Well, I understand that you dont want to blame her for everything, and that she has reasons to feel like she does. However, her demands are simply unreasonable. Even if she is very insecure and you dont want to make things worse on her, but she's taking everything out on you and you have done nothing. I mean seriously, she cant handle you playing video games or watching TV? Hell, I send good porn sites *to* my girlfriend and she does to me . But dont let her take her insecurities out on you by making you feel worthless (this is pretty textbook psychological to me, she's taking out on you what was taken out on her) or making you feel like you are in the wrong.

Just try to talk to her and let her know that you care for her but that she is treating you badly (because she is). Hopefully you will be able to take it from there and see what needs to be done, cuz none of us know the full situation or can fully help you out.

Good luck
