Recently, we were at a local bar together; there was a guy talking to me and, because our relationship is casual and we trust each other enough (believe me, jealousy is not a factor for either of us), I was talking to him as well (I was not necessarily flirting with him, but he was flirting with me) and some of my friends pulled me on to the dance floor. While I was dancing my guy sat down in the chair that I was in and the guy I was talking to said to him "hey, you're sitting in my girlfriend's chair". Knowing it wasn't true, my guy asked, "oh yeah, who's your girlfriend?" (knowing he meant me) and the guy pointed to me. My guy proceeds to ask him questions, "how long have you been dating her?", etc. Then he tells this other guy, "I'll bet you $20 I can get your girlfriend to sit on my lap." Well, now this guy changes his tune to, "I mean, she's my best friend". Anyway, he proceeds to tell this guy he knows he's lying and will prove it. He called me over to confront this guy. After I walked away, he told the guy, "guess what? she's MY girl (????) and I don't appreciate people lying about her". We laughed about the whole thing later saying, "what was this guy thinking?"
This last week we went to pick up one of his friends. I waited in the car and he brought his friend's mother out (who he had just recently met) and introduced her to me and then started joking by saying "this is your new competition, watch out". We were all laughing.
This is just minimal information, there are more incidents similar, but I can't go into every little detail. What am I supposed to think of a guy who refers to me as a "friend" yet treats me like a girlfriend and insinuates I am his girlfriend to other people?? I really can't read him and I'm really getting confused!! Personally, I think I'm falling in love with him (a feeling I have been fighting and won't share with him because it's often confused with lust - a feeling of which I know the difference from experience - and I have to be sure it is love that I'm feeling before I act upon it). Help!!
