birthday bash gone wrong

So my birthday was yesterday, May 23rd.
We had a party on the rooftop of my boyfriend's apartment complex. They rigged it so there were lights, music, and it actually looked pretty awesome when I finally got up there. The night was slowly turning bad, then turned good. It was up and down really. The only thing I like to drink is tequila, and they couldn't get that. So that was a huge bummer just because I hardly drank at all, all night.

I had a bunch of my NOVA friends come out, some friends from Richmond showed up off and on. So I'm glad that a fair amount of people were there. Good to see a few faces that I hadn't seen in a while.

The night was going good for the most part, then it started to get late around three a.m. maybe. Well something happened and these kids were yelling at the other one. I don't even know about what. I don't know how the verbal argument started, but then for some reason it turned into a physical one. Well out of nowhere some kid picks up a glass bottle and throws it. Turns out that the bottle shatters and ends up cutting up some kids face. Everyone backs off, doesn't know what to do, screaming, whatever. Well everyone starts to leave because by this time everything it all shot to hell.

So the next thing that happens is that Gregory decides to blame the entire incident on me. Noted, I don't have any idea why it started, what happened, and who it was actually between.. but because a kid from Richmond (where I live) through the bottle.. it was my fault. So everyone gets off the roof top and I don't know if it was because he was drunk or what.. but comes up to my face and starts bitching at me cause he's saying it's my fault. He says "let me point out the kid get over here" or something like that.. and I turn around and he grabs my arm as hard as possible to pull me over to him. It was weird because it was the first time he has ever grabbed with any force to get me to do something. I told him don't touch me, etc.

Then some of our friends helped clean up on the rooftop. I start walking away and Greg starts yelling at me that it's my fault. I'm halfway across the roof and I yell back that I couldn't do anything, etc. He just keeps screaming at me "it's all your fucking fault" so I'm walking as fast as possible trying not to fucking cry. I get half way down the stairwell, ran into a few kids, then when they were gone just fucking started to cry my eyes out. I ran to the apartment, got my keys, and went to my car. The window beside my car was bashed out, so I moved my car to the other part of the parking deck. I ended up just laying in my car for a half hour before doing anything. I was crying and so fucking mad and I didn't know what to do.
I eventually went back into the apartment, Gregory was there. He kept saying he was sorry, and he told me he loved me. That was the first time he said it. I'm pretty positive that it was completely out of the fact that he may of thought that he ruined my birthday.

Either way, the night went to shit.
