<human>: Could you distill the essence of the text into 1-3 sentences?

So this is a bit weird, but I'm FWB/sort of casually dating this girl. It's going well, but she started showing interest in another guy today. I got a bit jealous, but it's cool, because she's totally allowed to do that and I haven't made my intentions to be anything more clear. I like her but I'm not sure what I want.

Which is the issue that I'm looking to talk about here; I don't know what I want. I got out of a 2.5 year relationship, really serious (my first one) like a year ago, and now I'm kind of waffling between "I want something" and "I enjoy being able to talk to girls and have sex with no commitments". I do want someone in my life, but I'm not sure if it's now. Some background; prior to my last gf I could barely talk to girls, now I'm actually pretty successful. So

I'm not looking for anything specific, just advice and thoughts from other people who have been/are in this situation. She's a cute girl who's really sweet, I like her a lot, but I'm not sure if I want to give up the single lifestyle.
<bot>: Please talk to me if you've had experiences where you weren't sure if you wanted a real relationship or not.What did you choose? How long did it take you?
