Bit of a long post but need advice,

I work with this boy who’s abit of a player and try’s it on with every girl. We’ve always had a problem with each other but whenever we go out with each other and drink we attract to each other. We kissed and stuff. However I feel like I could never be with him with his reputation and since we’ve been speaking more frequently he’s all I can think about. I could never see my self with him because I’d be embarrassed because he try’s it I. With everybody

HELP
