I went to Kyle's house tonight. He was having a keg party in celebration of his house being all finished, and my ex boyfriend showed up. He was with another girl. She was not attractive at all. He was all over her right in front of me. People caught them having sex in the bathroom. Later someone came outside where we were all hanging out and said "hey do you want to stop ryden and that girl from having sex in your bed??" to Kyle and he went inside and came back and said "oh they're not having sex" and then I went to the bathroom and his bedroom door was STILL closed and they were nowhere to be found so I went to Kyle and said "Get them the f*ck out of your room NOW" and he said "well what am I supposed to say?" but he did go back there and got them out and they were ALL OVER each other saying goodbye to people and I was SO angry I grabbed my overnight bag from his room and told him I'm going. I went out on the street to wait for a cab, and my ex said goodbye to me and I said, after he already closed the door "f-you" and another friend's sister came up and gave me a hug and I said "How f-ing rude do you have to be to HAVE SEX with a girl in the bed you know your ex is sleeping in tonight"and she said she knows, he's a jerk, and right then her dad pulled up to give her a ride home. She said "just wait a minute" and she grabbed my hand and said I can't leave like that and took me in to talk to kyle. He said "whatever, she wants to leave, she can f-ing leave" and I was bawling and she said "You can't just leave her to take a cab home all alone! I don't care, she's alone, and she can't take a cab!" and he just said "whatever, she wants to go home, let her go" so she got her dad to drive me home. I'm bawling so hard I can barely see straight. I need to go cuddle with Layla now. I hope I can feel better. I'm sorry for rambling.
