Hey Astro - nice to have a man's opinion, thanks!
I feel that this guy's pretty shy too... he said something about being single or something when we saw each other last, made some comment or something, and I was doing something else, and I think he thought I thought whatever he said was weird and he completely changed the subject to something so off... he's a little unsure of himself around me, I think. Don't know what that means. He also made a joke about how I should "load up" and go with him and some friends somewhere this weekend... and I think I said, "You wouldn't know what to do with me when you got there" or something, because it was so a guy trip... and he completely changed the subject back to business then, too.
And... I just remembered this... he gets on the phone with this friend of his and says all these really nice things about me... joking, like, "Well, I've got this girl here, and she's (compliments inserted..." but never said anything like that directly to me.
So you might be right. I don't know.
