Advice abt girl

Hello,

I kinda have a small crush on this girl. To provide some context, my friend offered to set us up for my fraternity date party. She’s extremely lot, like I’m not ugly but she’s definitely out of my league. My friend also told me she wanted to go more as friends, so I shouldn’t expect anything to happen but if it does it does. I asked her to the date party and then I met her for like the second or third time the next day at the bar. We were talking for some time then we went to the dance floor. I went to the bathroom for like ten minutes and come back to seeing her making out w another guy. I was obviously a bit upset and left but it was whatever. Anyway, later in the month, she had her date party and took one of her good friends from high school, so it was whatever. Anyway, we had our date party eventually and it was really fun and we had a great time together. I think it was here where I started to develop feelings. The next week she goes to another date party with another guy and I just felt like shit. Then today I was hanging out with two of her friends (one of them was the one who set us up) and somehow she got brought up and they were talking about this one night where she met this guy, implying something. I also realized she went to another date party with this guy earlier in the month, and I’m assuming they hooked up or had something going on based on the way her friends were talking about it.

I don’t know l, I just feel really upset about it. Like I know it sounds bad but it just hurts to see her with another guy. She was actually really cool and we had a lot fun together, and it sucks to think that she could be talking to or even fucking other guys. How do I get over this feeling? Btw I’m still snapping her but nothing more.
