This is the first time since I've been on these boards that I've heard anyone get hit with "I'm not happy, so YOU should leave"! What kind of logic is that?!?
I would certainly suggest that you stay right where you are. Let your W make the effort to leave if that's what she wants.
Plus, I don't know what the laws are like where you are, but if you leave the home, it could legally be legally considered ass you 'abandoning' the M. And your kids. It might be wise to find out your rights.
