Search Results: deciding between two guys

So this guy named Kian and I are both freshman in college and we have been dating for a few weeks. This past Friday we both went to a party and got pretty drunk. When I showed up to his frat house, I found him but then didn't see where he went so I got scared that he had gone to the third floor with some other girl but he had just gone to sleep. I wasn't going to go to bed so I stayed up and all of my sorority sisters had left because I told them I wasn't going to leave without Kian, so I leaned onto my two friends Riley and Isaiah for support because I was pretty much left by myself since Kian was asleep in another room. During that time, Riley who is my (ex) boyfriend's best friend was trying to kiss me because he was just as drunk as me if not more. I had told him that it would be wrong to do that to my boyfriend, but other people in that house had spread a rumor that we had made out and my boyfriend got really pissed. We decided to go home and Kian would not talk to me so I called him the next morning and thought everything would be ok if I just talked to him about what happened but before I could he broke up with me and told me things were over between us because of what he heard. It's been a day since we've talked becaue I'm trying to give him time to cool off, but eventually I am going to talk to him and tell him my side of the story. He hasn't changed our relationship on Facebook yet so I'm hoping that's a sign that he's not completely done with "us" yet.. I honestly am so upset right now because I don't want to lose him and I just want to work things out without having to go through an actual break up. What do you think I should do with this whole situation? Anything helps, thank you!

Long Story short: I had a strictly friends with benefits relationship with a guy but one night I had slept with another guy as me and the other guy were not dating, never hung out and only met to sleep with each other so I didn't think it would bother him if I slept with someone else. He found out and got very angry at me. He shouted at me infront of all of his room mates and he called me some realy mean names. I decided after that night that we should not continue our friends with benefits relationship as I was confised by him and thought maybe he liked me. We didn't speak or see each other for 3 months but two nights ago we decided to meet up. One of my freinds who went to a party of his told me he was speaking badly of me 3 months later at this party so when i saw him I just asked him if he was saying things about me to people and what it was he was saying. He then lost it with me and told me. Starting calling me names and stupid again and this time I said mean things in response (please know I am not one to fight as i hate it, I dont call people names and I dont likebeing rude) but for some reason I was really hurtful and I know I hurt him by the things I said as he deleted me off of everything and deleted my number and said he didn't want to see me again. I feel terrible for being mean and feel as if I should just send him a text apologising just so he knows i did not mean what i said and that when he thinks of me it will not be negatively. I hate fighting with peopleor ending things on a bad note but I am scared he will be angry i text him as he delted my number and me off of everyhting so he clearly doesn't want anything more to do with me but I also do not want to leave things so negatively between us, so my question is should i send the text (I will also say i think it is good we no longer hang out but i just dont want things tobe negative between us) or should I leave it as he clearly doesn't want to speak with me anymore?
