I'm sorry to hear of this latest development! Honestly I think that's terrible. This is what I'm afraid of in my situation with the other woman who lives in our house. I already know she's not a good role model for our daughter. I hope the guy your wife chose is decent. I hope your kids don't realize what's going on and I hope they don't get too close to him in case he's not around for the long-term. I have to wonder why you want to meet him? That sounds traumatizing in my opinion! And really uncomfortable. If it doesn't go well with him you still have no power over your wife's decisions and how she involves him with the kids so is there any real reason why you have to meet him??
