I hope, hope, hope that things never come to anything but the best outcome for you Really!!
But.... you have a very complicated business sitch that you mostly rely on for you and your daughters livelihood, what would it hurt just to get some advice? And as far as what H promises you (like the house), my H's promises change as the guilt he had subsides, as finances change for him, and sometimes when the phase of the moon changes. He started from "I'm so sorry and I'll help you financially" - actually told my parents he'd make me rich, lol -- to I'll take you for everything if you see a L. It's weird. You don't have to tell your H. Maybe he's already had some advice and is not telling you, you don't know.
I read on a board recently - and this is a Canadian legal board (Aye!) - that a woman could not apply for alimony from her H after 3 years because ... since she went for 3 years without it she must not have needed it. You never know.
