Well, I wouldn't recommend it..suppose the shoe were on the other foot and you were the WA trying to get your feet wet in the M again, how would you feel upon hearing THAT?
I think you would be wise to give him the benefit of the doubt and trust him. If he ends up sleeping around on you, its because his heart isn't in the right place to begin with, not because you threaten to leave him if he does. If anything all that does is give him the ammunition to say..."well, you didn't trust me anyway, so this M wasn't really going anywhere so...."
Now is the time you try and rebuild the M based on the same principles it supposively was founded on..Questioning his fidelity might not be the best way to get that done, IMHO..
