Would I be stupid to cut her off?

I met this girl at a party a few weeks ago and we’ve been casual for the past weeks. For reference I’m 5’4 &120lbs, and she’s ~5’5 and significantly more attractive than me. We’ve been getting along pretty well, but it’s nothing serious. You can guess from my stats alone this doesn’t happen often, but now we’re hitting a point where she’s talking about wanting to be more serious and having feelings. I was developing feelings for her too, until I found it that she recently got with someone else. Even though we’re not exclusive and never agreed to be, and I would do the same thing if I had the opportunity, I’m still pretty salty about it. She asked me if I want to keep seeing her and idk what to do. I don’t see a long term relationship with her, but also don’t know how often I’ll have this chance. Aside from what she did, she’s smart, funny, attractive, has a good future and checks all the boxes. Don’t know if I’m losing a good girl here / being dramatic or if I’m a cuck and need to move on. I just need someone to keep it real w me
