Ok so me and my gf went out for around 13 months on and off. We had one break for around a month in the middle. So all of a sudden she doesn't know anymore and she thinks she wants a break. The same night we go to the beach and fuck and the next morning we fuck but by time I go to work at 3 shes already out with her friends and with another guy. And at first i thought it was weird but didn't think anything of it but then she starts getting really mad at me for no reason and doesn't want to talk to me whenever shes with her friends, but when shes alone she'll call me and text me and stuff. And when she doesn't answer me its no big deal.. but when I don't answer she gets all paranoid and thinks I'm with other girls.

So its been around 2 weeks and I found out that she hooked up with the guy she hung out with and told all her friends she doesn't love me anymore and she likes him. And this whole time shes telling me she loves me and wants to go out but just doesn't know if she can.

So basically what should I do? I still really want to be with her but she won't forgive me about stupid shit. And when I try to talk to her she gets all weird but when I leave her alone for too long she gets mad.

Tell her that. If she doesn't understand, or just plain disregards your input, drop her.

Yea I tell her all the time that when she does something its ok but when I do it its wrong.. The thing shes mad at is i hooked up and did some shit with her sister but it was like a 1 night thing and didnt mean anything. But she tells everyone she likes this guy and hooked up with him. So I think thats worse. When I tell her that she usually gets mad then we stop talking... or if she doesnt stop talking by then ill say something like you know you would completely flip shit if i hung out with a girl the same day i fucked you and told you that i didnt know.. and she says i know.

She like knows what shes doing is wrong but keeps on going. And when I tell her I wanna go out still she says she loves me soooo much and all this shit but hates me at the same time for everything thats happened. And she always says stuff like as of right now its a no but that doesnt mean its a no forever

Bury them both alive in the same box.

From personal experience, confront her, then disassociate yourself from her.
She isn't worth your time. Find someone who will really want to be with you and you wont have to work hard to keep a relationship with them.

yea i guess youre right i just dont get it.. like whenever i wanted a break she was all over me until we went back out but when she wants one she all of a sudden doesnt care anymore.. like on of our breaks was because she said she wanted to marry me and have kids and shit and i was only a senior in high school at the time so i freaked but now all of a sudden she "hates" me

Yep. Girls have no fucking clue what they want. And us guys are stuck not know what the fuck they want either.

It's just not fair

Ditch that cheeky whore and go fuck one of her friends.

You kissed her sister you dumb cunt. Figure it out man, this other guy will be balls deep in her tight wet pussy soon, and once he does, you wont ever get another crack at it.

Suck it up, princess.
