I will chime in as a couple that have never been before, but I do appreciate honesty in a guy. The off-putting statement to me was "wouldn't come back if he had someone". Why Not Come back? Perhaps what's good for the goose is not good for the gander? Perhaps he would not want another single or married guy to bring their "A" game to entice his own gal? I am totally about respectful flirting and fun. Let's just not have a double standard. If it is okay for me to go as a single and flirt with other married or attached women and even hook-up, it should be just fine if I am part of a couple to allow my other half to do the same.
