Listen. I think it's sad but true is this. A huge number of men can't be friends with women. Let me reword, single men can't be friends with another woman. If men tell you otherwise most are lying. Coming from a guy, and being behind the scenes and the things that are talked about is nuts. Guys want to fool around with most things with two legs. I wish this wasn't the case because I think it's unfair to women.

There are a lot of polls small school studies asking these questions. One video in particular I watched a little over a year ago asked 5 paired friends one question to the male and female friend counterpart. Would you sleep with and are you attracted to your female /male friend. All the female responses were no never. All the men were yes if Given the chance regardless of the females relationship status.
Sorry if that doesn't help much. I agree with the above poster that def tell your boyfriend about it and see what he thinks. I wouldn't want my wife or girlfriend being buddies with a guy at work who I knew flirts with her and doesn't care you have a boyfriend or husband, it's insulting and says a lot about that person. Do you want that kind of person around you with that character?
