My wife wants out !!

[Dom R]

I want to do the "right thing" for my kids to give them a bigger place to live.

your kids dont need "a bigger place to live". They need parents who love them, and are with them all the time.
Other than that, just basic food and shelter is all they need to thrive.

"a bigger place to live", is something that adults think they need. something that they can brag about.

throwing money at a bigger house for them, does not make you a better father. they dont need more money... they need you.
