hey, thanks guys for all the advice. Of course it was late and i just wanted to post my thoughts. I shouldn't of posted it without putting all the details in.
Essentially, I thought it was kind of odd that he stared for a moment. And then didn't talk much to me after. And second, it kinda made me a little uneasy, cause he says hes not gay or bi for that matter, and when we hang out he seems to like to rub himself though his closes where i can see. Amongst other odd signs.
In short, I've never been stared at by a guy (that I am aware of), never mind my own brother in law, and after some other things, I thought that he was kinda curious about me. Now, thats ok and all that. Hes a good guy, gay or straight. I just didn't want him to become shy or not talk to me, if he thinks i think something wierd had happened. And by they way, he hasn't said a word to me since, which is unusual.
Sorry for all the confusion. I should of spend the time to word it right to begin with.
