I just found out the guy I've been dating for six months is married. We work at the same place and I'll spare you guys of all the signs I missed and how dumb I was to overlook all the warning signs. But, I've found out he is now and also that he has been blabbing our sex life all over the workplace and bragging about sleeping with me behind his wife's back. He doesn't know I know yet. I am wondering now how to shut him up. I now have his wife's name, their address, and their home phone number. I also have all the texts we've ever exchanged and pictures from a recent weekend getaway we took. I'm wondering now if I should confront him and threaten him with this information in order to shut him up or any other ideas on how to get him to stop blabbing. I don't want to actually tell his wife because there are kids involved and I don't want to be responsible for breaking up their home and causing her heartache since she is an innocent party in all this. I've learned a valuable lesson from this and will never date in the workplace again but for my sanity and comfort at work. How do I make this stop?
