Help with mutal attraction and flirting with work colleage?

He is just looking for somebody to f***, maybe he does it to every new chick that is up at work. So just tell him that you dont think it is okay to talk to him, because he is married and you are looking for a serious relationship (even if you are not), because you already had enough problems with men (even if you didnt). So tell him that you just want to do your job and in case he keeps on trying to hit on you, even know you are completely innocent, tell him you will tell his wife and sew him for ual harment.
