I won't talk from what others are telling you to do. I got out of rehab 2 weeks ago. I wasn't segregated from man/woman and I think that was beneficial. My entire experience was up to 16 men and only 2 women. The entire month. It annoyed me because of the sexual sh*t etc. and the poop talk. But I made it work and it was amazing. The LAST thing on anybody's mind is sex with other clients. Especially if married. We are at our worst here and let it hang out. If you are worried about cheating in rehab, your relationship is doomed anyway. Let her go through rehab and immerse herself. You take care of you and the kids. It sounds like a big mess. Good luck on whatever transpires.
