Unwanted crush

I have a crush on a guy at work. I have tried to ignore him and the crush as much as I can but a couple of people seem to have figured it out and are laughing at me and making fun of me, including the guy I have the crush on. I am in a happy relationship and do not want my partner to find out as he is very insecure about these sorts of things from his own past experiences. It really makes me unhappy when these people make fun of me but I cant seem to stop liking him.

I love my partner and do not want to do anything with the guy at work - what can I do?

If I were you , I would just get a grip really an decided whats more important , your in a happy realation ship you say, then why ruin it over some guy who you think is cute, who you 'dont want to do anything with''', your setting your self up for all the p*ss taking, you need to decided what you want, thats just my oppinion so please dont think im a b*tch , trust I have my own men problems, an am no better than anyone on this site xxxx
