I like a guy at work. We're both in our 40s and single. He's very introverted but with the small group of people he likes (myself and 4 other men in the team) he's kind, generous, cracking wit and very flirty.
While I know he likes me I don't know whether he fancies me too. Today one of the other guys was blowing over his keyboard to get rid of the dirt and the guy I like cracked a joke saying he'd blow it for him later. They do hang out together sometimes although this other guy is married with children.
I've not had a crush in rl since teenage years as I was married for 20 years until recently (it was over a few years ago so as not to drip feed). I'm also really rubbish at social clues (it's possible I'm Aspergers though I would not seek a diagnosis).
I'm keen not to make myself look an utter fool. What do you think? Would a straight guy make a joke like that? I have no idea what to do next.
