I really like one of my colleagues, but he has a girlfriend. I think e fancies me, because he always compliments me, flirts, and at our christmas party he came up to me said hi and whispeared " you look absolutley beautiful tonight" and gave me a kiss. later on when everyone was a bit tipsy he started dancing with me and was holding my hand, and he told me again that he thinks im pretty. One other colleague tried dancing with him but he held my hand, pulled me closer and we danced again. But nothing else happened.
Few nights ago we went out again with work colleagues. He arrived late, I ignored him didnt say hi and he did the same. "awkward".
I kept catching him looking at me. then on the dance floor he gave me the look and said come here. so i gave the look too lol and went to dance with him again nothing happened. he was giving other girls a bit more attention but i continued dancing with other guy friends and looked like i didnt care...Later that night he asked what i wanted to do for after party and he will be down for whatever i wanted to do.
Anyways I really like him but he is in a serious relationship he lives with her gf.
Does he like me? shall I do anything about it? or completely forget about him.. HELP
