Profound Betrayal: so you're considering getting back with a man who dumped you for a string of flooseys because - now - he's ready to go to counseling, and you want to do something "in the interest of the family." You sure have an awful lot on your own plate to sort out. All your vehemence about what the OP should do lies atop what strikes me as a gushing wellspring of confusion on your part . . . along with you not coming to terms with the realities of your own situation.

It never ceases to amaze me the power that's attributed to "counselling" as a way to get people to be how we want them to be. "Counseling," IMO, is the most overrated process that Western Civilization has ever come up with.

(So not agreeing to marriage counseling was the "deal breaker." The flooseys were a secondary concern. That, IMO, is putting the cart before the horse.)
