Well, I still feel those lifestyles are perfectly acceptable in the right situation with the right people. My wife and I are very liberal and open-minded. In my situation, however, I think we made a mistake by pursuing this while our own marriage was rocky. Certainly, using hindsight, it was too soon after she shattered my trust with the affair. Now I'm constantly wondering if she suggested this lifestyle just to find a new husband. That remains to be seen.
That being said, I've noticed some positive things in the last couple of weeks since I've started with the 180. She's angry less, she actually asked to have dinner with me a few days ago (at the end of which she planted a kiss firmly on my lips), and now she has agreed to let me meet and talk to this other guy. Oh, and last night, at the end of a phone call where we were discussing kids' activiities, she actually said "I Love you". She said it very quickly, and I was so shocked I think I said it right back to her just as an ingrained reflex.
