u-turn: tactical question. Have u researched legal separation? It varies state to state, and you may even do it in your own home, but you can state those boundaries loud and clear if you need to. Your children are your priority 1 right now (or 1A - you need to care for yourself first in order to do the job right!)
It also has the advantage of not being an actual divorce.
