My girlfriend broke up with me 2 days ago and I'm really hurt by it. We had been going out for 2 years & 10 months. She left me because she said she didn't feel happy with me anymore because of what I did. And so this is what I did I ended up having sex with another girl to get revenge on my girlfriend. Now hear me out my girlfriend had sex with another guy our freshman year now with that said we had been going out since the 7th grade ok. But we had been going out off & on. However she had started telling me she loved me after the first few months. And you know she was the first girl to ever tell me that so I felt special. Of course I said it back to her and stuff and I really did mean it. She was different from every other girl I had dated and I was different from every other guy she'd dated. But ya our reasons for breaking up were because we wouldn't talk a lot. But she's a very beautifull girl I swear she's model beautiful and I wasn't exactly mr. georgeous himself so I was scared to talk to her I didnt know how to. But after when we got into high school I grew out of my shell and I was able 2 talk to her without being to nervous. And so we started dating again however we had started going out again for about 5 months and she had started telling me she loved me again and stuff and I said it back and as far as I knew she meant it cuz i honestly did. but we ended up breaking up for some stupid reason I dont remember cuz it was so stupid but the next day she was going out with another guy and I was like what the freak! I thought u loved me how could u just move on that quickly? But idk she ended up breaking up with him cuz I guess she realized he wasn't the one. But thats' not all she did she then went and started hanging out with this senior guy who she then had sex with. Not only that but she tried getting with me right after that too. And well I didn't know she had done that cuz she never told me. So we started going out again. Only soon after that my cousin told me what she did and I asked her about it and she said it was true. And I got all hurt and I asked her how could u do this to me? I never did anything to u to deserve this. Why? Why me? And all she said was she was sorry and that she didn't know why she did that she was being stupid. Even then I didn't break up with her though I still kept going out with her. However after that she started talking to other guys even after I told her I was jealous. And I quit talking to girls for her because she told me she would get jealous too. However I wasn't as hard on her as she was on me. I didn't really care if she talked to other guys just as long as they were friends and nothing more cuz then I would start to feel jealous. And so she was telling them that if she wasn't with me then she would be with them. which in my opinion is so messed up cuz how could u do that if your with someone who u "love so much"? So I got really hurt and i asked her why she did it and once again she told me she was sorry and she didn't know why she did it. So I was willing to still give her a chance with me. Not only that but she also started getting rides from a guy who she personally told me she liked and this guy was a manhore and he liked her a lot. He would tell her to hook up with him and stuff and she would say no no no. Or at least thats what she told me she would say anyways. But if i would've done that she would of thought that I was cheating on her or something cuz she loves to jump to conclusions even though I've done nothing for her to believe that. But anyways we were doing good a little bit of fights here and there but nothing to serious. However we were gettting really serious she told me she wanted to marry me and have my kids and that made me feel so happy because i really love her and I would do anything for her I would give my life for her and I felt the same way about her too. And she was telling me how she would never leave me because im just to great and she's lucky to have me and be with me. she thanked God for giving her an angel. Which ps before I came into her life she was a drinker/smoker/hoe (sorry she had dated just about every guy in our school). But when I came into her life I changed all that I got her back on track I got her to quite drinking/smoking/being a hoe and I got her to start playing sports and now NMSU has offered her a full paid scholarship if she plays basketball. Which because of me is possible. I turned her life around.But ya we were so in love and then the most tragic thing happend we were arguing over something so dumb and then she said its over I can't take the fighting anymore. When she said that I got so hurt and so angry. Cuz i couldn't believe she would leave me after all that we had been through and especially over a stupid argument? so i wanted revenge I wanted to hurt her the way she hurt me so I went and had sex with another girl and i didn't tell my girlfriend about it after we got back together. I wanted her to find out the way I found out (from another person). And so she did and she was so hurt and she asked me why I did it and I told her it was cuz she hurt me really bad and I just couldn't take it anymore. So she held it against me for like 5 months until she finally said she forgave me. Cuz i told her i really did regret it which i did cuz i was being stupid and i let my emotions cloud my judgement.(ps i told her I was sorry and i regreted it about everday for those 5 months) After that i thought we were fine but i guess she never got over it and until recently she told me and I tried telling her how sorry I was and that I regret it so much cuz i do and if i could go back in time and change it i honestly would but she said no i can't believe u did that to me and i'm not happy with u. and just basically making me feel like crap. I begged her to please forgive me like I forgived her for all the mistakes she's ever made and she said I do forgive u I just can't forget about it. and ever since then she's never let go and its been about 2 weeks since we started fighting about this. And I really love her from the bottom of my heart and i would give anything to be with her she's my everything and she's the only girl i wanna be with. And i honestly do regret my actions i should of been the better man but I let revenge get the best of me. so my question is what can I do to get her back. we are currently friends right now and she's trying to "build her relationship with me back up" but she's over there flirting with other guys and stuff and she doesn't know if she will go out with them or not. So please what can I do to restore our relationship. I dont wanna lose her I can't lose her she means everything to me without her im nothing. Please somebody give me some advice im desperately in need of assistance. Thank u for reading this long message sorry it was so long its just u needed to know the whole story and thank u once again.
