When men are in MLC there like dogs. Being with the OW has well to say it nicely taught him a few tricks. He probably wants to try these tricks on you or wants to get you into something kinky. I suggest you keep the talk going but only talk no matter how much you feel like having sex. There's a term for WAS who want both their spouces and OW. It's called "Cake eater" they want the best of everything. A typical selfish MLC behavior. Hopefully your H isn't having an MLC - its a terrible situation to be. Now I have a few questions for you. First how old are you and your H? How long have you been married? Any children or are you pregnant. Finally has you H experienced any strange behavior lately. Maybe lost a lot of weight, tatoos, piercings been going to the gym lately. This will help determine if he's having an MLC.
BTW - I've been at this for too long. To long of a time to go without having any sex and I don't think my W is having an affair.
