"But if he leaves the home for sanity reasons he has abandoned all rights to home."
Leaving the home will not diminish his rights to the value. Does he have access to savings/checking accounts? Just take the $10K, load the tools up his vehicle, and leave. Then, initiate divorce. Floride is a no-fault state; neither party can stop it.
Taking all the furnishings out of the house while children live there is a bad idea, and isn't in their best intersts. I wouldn't go that route. I'd just wait for her to go to work or whatever, and take what is pre-marital and tools and leave. No one should stay where they are being psychologically beat up everyday.
