T - We don't know if Josh's relationship is toxic. It's displaying Toxic traits NOW as all marriages do when they are falling apart. Rewriting of history happens on both sides of the fence. Only time will settle the muddy waters of emotions... but sadly most don't last here long enough for us to truly help them.
Exactly it is clear he doesn't want the marriage to end. Tell me CW how telling him his wife deserves to go out and find good sex is empathetic.
