I've been working with a guy for 4 months - admittedly when I first met him there was a spark and he is probably someone I would have dated in another life (I have a boyfriend, he has a lovely girlfriend).
I feel like things changed after a company party recently, where he stayed close to me for much of the night (his girlfriend was also there, but often chatting with other party-goers). At the end he asked for a hug (didn't do this with other colleagues), but I just thought he was being friendly.
After the party, I felt his behaviour toward me changed. He started offering to share his break time snacks with me and no one else (which I found a bit embarrassing) and started going out of his way to do little things for me. He started always sitting or standing close to me, which I think our manager picked up on.
Last week he made a racy comment when he saw I had been clothes shopping (really, it wasn't that exciting...) and today he said 'so you're really wild then huh?' over something completely innocuous. When he said this our female manager, who was also in the staff room, said his name sharply, as a mild reprimand I thought.
Is he just having a bit of a flirt to make the work day pass quicker? I find his comments a bit embarrassing more than anything!
