<human>: So this is kind of a weird/novel situation for me, and I'm looking some guidance from those wiser than me.  

I met this girl a couple of weeks ago, we hit it off and have gone on a few dates.  I stayed the night at her place on our second date, we mainly just cuddled and kissed a little.  On our third date she told me that she talked to me about this other guy she's been dating, and he wasn't comfortable with her having sex with other people, so that was that.  She made it clear that they weren't in a relationship though, and she wants to keep hanging out with me.  

I don't really know what to do about this.  I've never been attracted to a personality as much as I am to hers, and I really enjoy hanging out and talking to her.  It honestly doesn't really bother me that she's having sex with other people right now,  but I know that if I keep spending time with her and getting closer, it would bother me.  It's also strange to me that she's decided to be in some kind of exclusive not-a-relationship with this guy while still wanting to go on dates with me.  Any thoughts are appreciated.

Can you summarize the given text in a few sentences?
<bot>: Girl I've been dating is sexually exclusive with another man, but wants to keep hanging out as something more than friends.
