I Am Confused

There’s this guy.. can’t decide if he’s into himself and thinks I like him or if he likes me and thinks I like him.. or just likes me. He’s stared at me a little longer than “normal” when we walk by each other. Like I don’t know if he wants to say something, but doesn’t or what his deal is. He’s said my name loudly when asking about me like he was trying to get my attention (I was in the room). He doesn’t really say much to me, though. He once sent me a short text that was suggesting he noticed my butt. I didn’t respond because I was confused by it at first. He’s never texted me anything like that since. He knows I’m in a committed relationship. I’m just curious, you know? I’m not going to leave my SO for him, but it’s just one of those things that’s going to bug me until I find out.

Guys.. what are your thoughts? I understand I didn’t give much detail. Personally, I think he’s a player and a couple times of smiling back at him got him thinking I have the hots for him or something.
