Does he like this girl? Please help!?

I Hav been sort of seeing this guy who I think is probably the nicest guy I've met but something has been bothering me lately, I asked him if we could do something this week and he said he was free Friday because he is busy on every other day. So on Wednesday I was on Facebook and I went to his page and it said 'Checked in' at the train station with some girl I've never met before, but what bothered me was that an hour later he deleted this check in and it got me thinking what is he hiding? So I confronted him about it by asking him what he did on Wednesday and he said he played squash and then went some where else. I said what did you do at this other place? He said I saw 2 of my friends, I said name them, he was hesitant to tell me and got angry at me and said why? And I said Coz I'll know if your lying. And he said Aw fk that, I'm not allowed to see my friends whom aren't male. I was getting ice cream with my friend jess and my friend Bec wasn't happy that she hadnt seen me in ages and I said I was getting the train home and she took me home. Satisfied!? I said I have male friends...but they are all attracted to me so if you tell me that there is no attraction between u and your friends I know that's a lie! he didn't reply for ages then I said I wasn't seeing him on Friday and he said Fine. Am I right to think badly of him in this way? I just know guys and girls can't be friends! And also am I crazy???!!! Dies he like one of these girls??????
