Update 4:

I'm holding up surprisingly well while my wife is out-of-town with the OM. She left before 5 a.m. They're supposedly with 2 other couples, all his friends. I started off the day with a heartfelt prayer to the Lord and some Scripture reading (Book of Job!).

In the afternoon, I brought my kids to a birthday party at a local swim park. She texted asking how we were and to tell the kids she loves them. I went ahead and told the kids but I didn't have the chance to text her back.

She called later on but I didn't hear the ring. I'm debating whether to call her back or not. She comes back tomorrow morning.

Spoke with my C briefly today. Told him that I feel my WW has crossed many lines. In addition to this trip, last night she made out with one of her female classmates. Yes, my wife was bi-sexual before we got married. And she also told me she's been having "dirty-text" with the married brother of a classmate whom she met during one of her nights out with her classmates. She's just out of control. I asked the C what he thinks of me telling her to live someplace else. The kids and I can't be exposed to this kind of lifestyle any longer. The C says if I feel she's crossed a line then I have every right to insist she live somewhere else.

I'm trying to formulate what to tell her. Any suggestions?
