I have a married co-worker who has constantly been flirting with me from day one and we're talking about two years now.At first it started with the eye contact that He still does, and now He says things that are sex related,but as a joke.I really don't get it,because He hasn't said anything to Me about having an affair,yet He gets upset when He hears Me talking about any Guy.I just figured He'd give up flirting with Me since nothing Has happened.He flirts with Me as soon as I get to work.What is His purpose in doing this?
