Ladies this is likely common knowledge at this point, but its important to remember that men can have "no strings sex" without batting an eye over it.

This is akin to those teenage girls thinking "Well he wants to have sex with me, so he must love me right?"

I am not dismissing the idea of sex as a marriage repair tactic either, but you need to be warned it may not register.

I strongly suspect your H waterbur is NOT done with this affair and as Pup said earlier they have secretly just postponed it until the D is finalized.
