My GF taking revenge on me !!

I'm in a relationship for the past 1 year. At the start of relationship we've decided to marry and lead a happy life. She used to say that she loves me more than herself and asked me not to leave her even if she asks me to. I gave her my word that i would never leave her and she gave her too. For the first few months she used to be too good. We have physical relationship also. That time she was so crazy about me. We had so many good times and of course hard times too. But later on she used to complain a lot that i don't care for her and i don't love her when actually i do love her a lot. She is so jealous such that she doesn't want me to talk to my friends also. Even her friends used to tell me how much she loves me. She used to be over-possessive of me and in that process started abusing one of my friends. So i replied rudely to her. Since then she started behaving in a strange way. She gets angry if i don't wear the shirt she asks me to wear, if i'm late when we plan to meet, if i don't call her often etc. She feels i'm being so rude to her. For each and every small thing she gets irritated and says that she wants to breakup. I told her lot of times if she has got any problem let me know that, we'll talk and solve our problem. But she never tells me what exactly is bothering her, instead she keeps yelling at me. She has been avoiding me for some time and keep saying that she wants to breakup again and again. But whenever she leaves me, she'd call me back and say sorry and she loves me a lot, that i'm the only one she wants to spend her the rest of her life. She even used to lie for some things. When she is in a good mood she'd take care of me like anything. But when she is pissed off she won't even give a damn. Recently she told me that she was just faking for the past few days and she doesn't love me anymore. She wanted to get this relationship over and blocked me everywhere on her friend lists. Actually i wasn't surprised when she said this because this is the kind of stuff she does when she is pissed off. She has a feeling that i hurted her a lot and thats why she's been taking revenge in this way. What bothers me is.. why is this girl behaving in such a unusual (maybe usual for girls) way ? To be frank she has a feeling that she doesn't look good. She always feels inferior about that and thinks that i would leave her, go out with some other girl. Sometimes when we go out, people used to see her weirdly. Because of that she never came out with me in the last few months. Maybe i've made her feel bad but she is the one whom i want to be with. I wanted to hold her hand, kiss her forehead and say sorry and that i love her so much. But she dint give me that chance.I've got so many proposals, still i wanted only this girl. I helped her a lot in so many ways. I never put up any restrictions on her, always treated her equally. Still she believes i'm rude and made her feel bad. Man.. I don't know how to express this feeling but i want her like anything. I'm more like a tough guy, i made fun of so many girls, i never really feel bad for anything. But this thing hurts me a lot. Tears are just coming out of my eyes. I'm just becoming so emotional. Being haunted by her memories. I don't think she is interested in some other guy because she's not a cheap minded girl. While we have this physical relationship i don't think she would go for some other guy. So i guess she just wants me to feel bad and make me feel guilty. Why doesn't she believe me !!?? I tried everything to convince her that i love her a lot, and i would never be rude to her again. But she is not in a mood to listen to me. Do i need to wait for a while or keep trying to talk to her ? I have a feeling that she would come back to me.. as this happened a lots of times before. I just want your opinion/suggestions. Thanks for going through my post patiently smile

I too have faced very turbulent times in my life due to a very cordial relationship suddenly gone sour. I took advice from a guy named Erwan Davon Based in San Francisco. He actually put my life back on track. May be if any of you need some advice can search google for Erwan Davon Relationship Blog.
