Hi Reddit, 

So there is this man, and he is seriously so attractive and magnetic. I have only talked to him personally (one-on-one) a handful of times, but we have emailed each other quite a bit, always with work related things, but I have asked him for advice and he seems to really care about the things I've come to him about. 

The other day we were attending a conference together for work, and he was lecturing for part of the conference, and he angled his body toward me and seemed to make a lot of eye contact with me. Each time I talk to him alone, there is so much intense eye contact going on and I'm not sure if I'm reading that wrong, or if it's a sign that he may be attracted to me as well. I've been flirty with him and he's definitely flirted back (I think), but he is very socially awkward, so I don't think I always notice when he's trying to flirt with me.

He has openly checked me out before in front of me, and when I went to his office to discuss some paper work with him yesterday, I just got this feeling like there was chemistry there. 

I know this must sound stupid, but I really feel like there is something there, but I don't want to make myself look like a fool. He's divorced, so there is not anyone else in the picture as far as I know. 

If these aren't really signs that he's interested in me, could you guys give me some advice to maybe pursue things and let him know I'm interested.
<bot>: Older work colleague may be sending subtle messages that he's interested, but I'm unsure. I'm totally into him though. Please give me some advice.
