Relationship Help...

Okay so, I know that I will probably get spammed or told to fuck off or shit like that so just leave that out, please.
I am in a relationship with a girl for what has been about a year, and as of recent actions she keeps thinking I am going to leave her, and it seems like she is trying to push me into breaking up with her. She keeps acting like a complete nutjob the second I talk to someone other than her (not just girls, and no I am not bi). She complains that when she calls I have nothing to talk about and it seems like every single problem she has, she feels it is my fault. She cries when I tell her I don't know to pretty much any random thing, she cries at the drop of a hat, and when she's happy she will cry for no fucking reason, and when I ask her whats wrong she won't tell me. She is being, well, a psycho. She keeps telling me that if I wasn't in her life she would kill herself, then when I confront her about it she says "Kidding" in a sarcastic way, and then stares at me.
I really need help. I don't want to leave her, but I can't see myself with her any longer if she keeps acting this way...any help is greatly appreciated.

Look up borderline personality disorder.  She could be this retarded and annoying for the rest of her life.

You should stop sleeping with her.  I know incest is fun and all, but sisters -- especially younger sisters -- get really clingy once you start dicking them.  You have to nip this thing in the bud before it gets really out of hand.

If that doesn't work, just get her pregnant.  Nothing says "Leave me the fuck alone, bitch" like mutant incest babies.

INCEST IS BEST
PUT YOUR SIS TO THE TEST
