Ox, you should really, really listen to GabbysMom. You are on the wrong track.
Totally agree. In all my time on these boards (which is a LOT), I don't think I've ever seen another poster combine so much PASSIVITY with yet so much AGGRESSIVENESS. Ox is neither laying any strong boundaries, nor is he leaving his wife alone, either. He allows her to continue her affair, with near-cuckold status for himself, all the while picking at her with "how's your boyfriend" "did you kiss him?" "did you sleep with him?"-type jabs.
Absolutely, positively the WORST hybrid approach you can do, in my opinion. As much as I'm not a big fan of the totally-soft (what I call "Bo-Peep") approach of just waiting out affairs while working on yourself, it would be far better for him to do even THAT than what he's currently doing.
