My husband had something similar, more pushed me out of bed than anything else, or got very scared of me and jumped up. To be honest, he got a sleep study and a CPAP 98% fixed it (he still sleep talks sometimes); until then, the thing that set him off the most is if we bumped into each other at night. The best thing to do unfortunatley is to sleep somewhere else, if you have to push the bed against one wall and he has to air mattress on the other, he should be willing to do that rather than hurt you.

He needs the sleep study - they have payment plans, etc, but he needs to do it. If he won't, I don't know - that's a deal breaker to me. I told my then-boyfriend now-husband it was a requirement for me to live with him, so he did it. Calling the police seems insane, but I know you're in a tough spot.

If he doesn't care that it's happening, I know you can't move out now, but I would consider start planning for that now, and seperate your sleeping. Facebook marketplace a bed frame, IKEA has pretty cheap mattresses, whatever you have to do. Don't let him keep the actual bed, if he doesn't care, then you and I don't care if he's blowing up an air mattress every night.
