My question for you Arsene is, does your wife respect you? She is not likely to fall back in love with a man she doesn't respect. This is part of the bases for the CB approach. You stand up for yourself, set boundaries and stick to them, and she may start to show more respect for you and see you in a new light. Maybe even as a guy that will not wait around forever for her. I think this can be done without going dark though.
Michele talks about this on pp. 122-123 of "Divorce Remedy," when she talks about the "Nice Guy" approach. I think some people would be stunned to read what she wrote about it, and should look it up.
