My FP got a girlfriend when he had told me a week before he wasn't ready to be in a relationship again. I got mad at him, but he didn't take it offensively because he said it was justified then said he was sorry. Since then he will barely talk to me and I am getting incredibly angry at the girl for stealing him from me. 

He and I were doing really good, talking a lot, and seeing each other more frequently up until \*she\* came around. I'm getting angrier and angrier the more he ignores me for this new, stupid girl, and I'm finding myself having to fight off the urge to manipulate him or find her and slap her upside her head. 

He's going to fully leave soon enough here with the way things are going, even though he said that we were still friends and \*nothing would change except we could no longer hang out or do anything sexual\*, and I feel so helpless. He's going to eventually disappear and I'll have nothing left - no friends, no family, nothing. He was all I had and even though he treats me like shit and can be an asshole, I need him. Don't get me wrong, I'm mad at him too, and I hate his ass with a passion for doing this to me, lying, and letting this wh\*re get between us, but I can't lose him. I need him to survive. 

I'm spiraling out of control.
