Found the guy I’m hooking with, with someone else

Okay basically this guy and I have been hooking up. Well the other day I asked him after we had morning sex if he wanted to come over tonight since I didn’t have work. He said he couldn’t because he was going to dinner with his sister. No big deal to me so my friends and I decided to go to a party on campus ( I’m in college). Well I needed to go to the restroom so I headed upstair. Right next to the bathroom door was the guy kissing a girl. He saw me and I ran out as fast as I could. I went through the back so he wouldn’t find me and called an Uber. Went to my dorm and fell asleep. Found the guy in my room in the morning (he has a key bc he’s been sleeping at my place and sometime needs to drop off stuff). Here’s the thing, he has been giving me more than fwb vibes for the past two months. He brings me dinner, gets me coffee, massages me after yoga, he stays the night, will sleep over and cuddle without even having sex, call and talk to me about his problems. Also literally last week a guy asked me if he could have my number at a coffee shop and he came up to me pulled me by the waist and don’t the dude to fuck off she’s not interested. I’m not saying that we are in a relationship however I thought we were more than sleeping buddies. Also we are EXCLUSIVE fwb. I told him we needed to be that because he wanted to have sex with me without a condom. However I said that only could happen if both of us get tested, I’m on the pill, and if your only sleeping with me (stds and shit). He agreed and have been like this for 3 months. Well he told me this morning that I shouldn’t even think we were more than sleeping buddies because he told me before he didn’t want a relationship. When he said that I kicked him out of my dorm. I know we aren’t bf and gf. I know that, but he told me we were exclusive fwb. Seeing him last night kissing another girl I don’t know if he has slept with someone during our time together. Here are our text from last night. When he left my dorm. He kept calling me and calling all day.

After this he called me and called me and I finally answered. He was crying telling me how sorry he was and doesn’t want to lose us. I don’t know what to do. He wants to meet in person but I don’t know if I can face him. I don’t know if I should forgive him. I don’t know what to do. I opened myself up to him which I never do.
