One other thing, the OM is not the cause just a symptom of your problems. She doesn't respect you so you need to be consequent, calm and have all the rules of engagement at your fingertips. Get professional advice about how to go forward but now that you've set your boundary just maintain it. Don't make comments about the OM, in fact, treat him as a non-entity as long as he is not around your daughter or home. He is nothing. You need to GAL and be the better option, either for your wife or some other wonderful woman out there. Concentrate on you and your daughter. She's worth whatever you need to do to protect her and place her in a safe environment. She should never be afraid to talk to you and never put her in the middle. Don't use her to get information about your wife, simply tell her you want to only know if the OM is present when she's with your wife. Nothing else! You love her and let her know that by lots of hugs and attention. Hope your Saturday goes well and that the 2 of you get out and have some fun!
