I really need her back

my girlfriend ended it with me last week after dating for years, she told me she wanted us to be friends and didn't feel the same anymore, so i got angry and decided to make her jealous by talking to her sister on FB. YEAH she hates when i talk to her sister because we used to flirt way before i got together with her. ( PLEASE DON'T JUDGE ME PEOPLE) I know it was stupid but i didnt know what to do. So my girlfriend simply decided to cut me off her life, she deleted all my pictures, took me off on msn and blocked me on fb, she won't answer my messages or my calls.

I really love her and I just didn't accept that she didn't love me anymore, we always got along with each other , like soul mates,
she used to laugh at every of my jokes even if they were lame then all of a sudden she hates me. Do you think she still has feelings for me? because she got angry when i talked to her sister on facebook, is that a sign? Idk what happened she seemed to be so in love with me, she wont tell me why she apparently fell out of love,i tried to talk to her but she's been avoiding me.

I don't wanna any other girl because it ain't the same thing. they don't make me happy like she does.

You messed up. Don't expect her to come crawling back for you.

I'm in the same boat as you man. She left me 5 weeks ago to be "single, and free" but she started dating right after. Now she has a boyfriend and they sleep together and the whole 9 yards. She seems so happy with him. She told me the same thing yours told you, that "we just don't have "it" anymore". We were together for years, and I just know shes the one for me, no one else is interesting at all. I ended up blocking her to stop seeing all of the stuff he posts on her facebook. Not trying to make this about me, I just know it helps sometimes to know you aren't the only one in this situation. I really want a chance to bring that spark back, but it doesn't look like I have the chance right now. I hate hearing it all the time, but we may just have to wait it out and see what happens.
