Is this friendship or what from a Scorp Rising?

I have a random question about a guy I know.

He was initially my calculus tutor, but pretty much along the lines he started becoming more open with me. Like for instance he randomly started telling me about some ex girlfriends of his, and even showing me them on facebook. Then he would tell me that random girls are cute, or that some girl put a note on his car giving him her phone number.

I just thought we were becoming friends as we exchanged phone numbers, and then he would say things like when am I and my friend going to the bars downtown. I had tried to get him to talk to some of my friends, however he said it would be awkward. Even one example was I was getting help and I had said something in passing about not hearing him, and he said that he had been hanging around a girl he was talking to too much (keep in mind I didn't even know the girl).

Even if I talk about ex boyfriends he doesn't really add anything, an example is I told him I was still in love with my ex, or if I mentioned anything he would stay silent.

For instance when I was in one of the bars he was at we talked (as he was playing pool) and then I said I would be right back. And he was like you aren't coming back. And I said I was. I did, but when I did I brought a male friend of mine (who I'm not into AT ALL), and he barely spoke two words to me. And I told him I had to go, and he was nice and said bye. And when we I have gone to bars he won't talk to me unless I'm alone. I meet his friends, but that's about it. He actually doesn't talk to girls when I'm around (well at least for both the times I was there around him)

I just find this all strange that he does talk about this to me. I initially thought it was because he thought of me as his female pal...but things started to change when I noticed that he would bring up stuff about relationships and I didn't even bring it up. Or he and I are talking (about my car mind you lol) and he'll say he's getting distracted because of sorority girls that are rushing on the field across the street. Or how when I left after the night I had my friend with me at the bar he ended up taking a girl home (even though he denied sleeping with her) and then telling me about it (as in he had to take her home because the guy he was playing pool with was a jerk, but didn't hook up with her because of her teeth). Another instance was when we hung out last Friday and I was drinking and was a bit flirtatious as a result, he as usual was telling me about this girl who was trying to talk to him that he wasn't into.

I did recently say something about my ex and him being in town, and then he busted out and told me he had that day talked to 4 of his exes. Which I thought he said because he was trying to one up me.

I will say I am kinda into him, however I don't know if I should ask him why we talk about this or just let it slide. Or am I his female gal?

I deff agree...I am into him, I just wasn't sure if this was Scorp behavior. I deff know he said something in passing about all people have ulterior motives or hidden motives so I do think him talking about relationships is very much so calculated. However, I'm not sure what the motive is for this though.
