<human>: Can you give me the gist of the text in a nutshell?

I hit it off with the girl about a month ago at a birthday outing of a mutual friend.  Got her number that night and went on a couple dates that went well.  About 2 weeks later I was out of town and get a text from that mutual friend that was at a bbq with her that says "I think she has a bf."  Apparently she was all touchy with this guy.  Do some investigating and find out from some other people that shes is definitely seeing somebody, but I do not know how serious it is. 

 I get turned off and back off for a bit, but she contacts me and we continue talking and flirting via phone/text.  Some drama ensues with some other girls that we are mutual friends with and stuff starts to get weird (long story, can't get into it).  I say ok this is enough I need to defuse this situation so I tell her I like her, but I understand your situation and respect your seeing somebody else so I'll back off.  She responds in saying there is no one else and I'm dumbfounded. 

Kind of left it at that and I'm supposed to see her tomorrow with a group of people where I plan on confronting her and finding out exactly what is going on.  I am not cool with being the other guy and even though I am crazy about her I can't go forward unless there really is no one else.  I do not mind her dating multiple guys if shes honest about it and none of them are considered boyfriends.  Exclusiveness is important once we are at that stage, but we are definitely not there yet.  What does this sound like Reddit?
<bot>: Meet girl, hit it off, and go on dates.  Find out she has a boyfriend.  Confront her about it and shes denies it.  Seeing her soon and plan on getting truth out.
