"H, in order for us to have sex, you would have to move out of the house, attend counseling consistently for 6 months, give me total transparency on your phone and email etc to prove you aren't cheating, etc. Once you've done THAT and shown true remorse and a genuine desire to change, I'll consider it".
Sad, though, since we all know your H isn't capable. Still, that's what a TRULY remorseful spouse would do; don't settle for less!
