I've been hanging out with this girl for a few months causally hooking up, which turned into us spending more time together, and eventually she wants me to commit.

She told me she's into me, wanting a relationship, but something is making me hesitant. I don't know if it's past bad relationships, etc but I just get this feeling of doubt about it.

I don't know if it's her, relationships in general, or what that has me hesitant to commit. I enjoy spending time with her, sex is good, but it makes me nervous for whatever reason.

She started seeing other people which is in her right but really bothers me when it shouldn't. Usually if I'm just hooking up I don't care if they date others, but this bothered me for whatever reason. But I don't feel "fuck yeah"about getting in a relationship either.

Have you been in this situation? Is it just scarcity mindset getting me upset? I'm not currently seeing anyone else (although I was last month when she started to) but I also haven't had a real strong urge to do so either.
