<human>: Condense the text into a few key points

My boyfriend and I dated for almost 8 months, both in college and are currently long distance. I went to a friend's birthday party over the weekend. I didn't eat any dinner and drank way more than I'm use to. I blacked out and can't remember anything that happened. My friends told me the next morning that I was making out with this guy that we went to high school with. I couldn't believe it. I absolutely love my boyfriend and would never think to be with another guy while dating him.
 
I was disgusted with myself and ended up telling my boyfriend the next day. He was obviously furious and upset. He tells me I need to figure out how to fix this and words don't mean anything to him.
 
He's very against cheating and has already threatened to sleep with another girl. I do not remember a single thing from the night. I need advice. I would like to work this out to either the point of getting back together or just to the point of him not hating me. We are both each other's first loves and he continues to call me a "cheating bitch." I know for a fact this will never happen again.
