Would it be wise to confront the W at the IC session I was thinking saying something like when you drink you do dumb things like text the OM and this upsets me? This last week she is acting like everything's ok wants to hang out, have sex and do more things together.
Wants to sweep it under the rug. Is it wise to draw the proverbial line in the sand?
There's nothing wrong with enlisting your MC's help in communicating your boundaries to your wife. I would just be sure to include not just "texting OM when you're drinking," but that "I will not live in an open marriage. I cannot feel safe in a marriage where you're in inappropriate contact with another man, and are being secretive with me about it. This doesn't work for me."
