Search Results: arguments over little things

So this guy I was sleeping with, he's very closed off from his emotions, and has this confident... cockiness about him, like sort of conceited but not... one day he asked if I had been sleeping with anyone else, and I told him no, and he said he wasn't either. And when I asked if it means we couldn't see where things go with someone else, he asked if I had anyone in mind. And I told him I did.
About 20 minutes later, one of my friends text me, telling me he was talking to her on plenty of fish/facebook. (She knew about me sleeping with him, that's why she contacted me, but he didn't know her and I were friends.)
And while he talks to her, the very first thing he says is, "You know (my name)?" and she goes, "Yeah she's one of my best friends.." She thought it would have been weird if they hooked up, and he says "I've never met you and just because I did something with your best friend doesn't mean it's weird or wrong. She doesn't like me. It isn't wrong."
The only reason he went on P. O. F. is because I told him I was thinking about dating someone else (cuz it seemed like him and I were going no where, but I didn't say that part.) We got into a little argument over it and he said he thought about making whatever we had into a relationship, but then he realized, he really doesn't know much about me or how I feel about him. We've still been sleeping together since..
But the part that gets me is he only says "She doesn't like me"...
If you didn't like a girl would you say "We don't like each other?" Or am I reading to much into this?
Does he at all sound into me, or everything is just to get me to continue to sleep with him while he looks for someone better or something?
