Sweetie, these are classic power and control tactics on his part.
If you want to leave, start working on your plan. Just doing that will give you some relief--light at the end of the tunnel. Keep it on the down-low and do NOT share that you're even THINKING about leaving. If you need more support and help with planning, contact your local DV agency--they can help you think this through and come up with a good strategy.
Hugs,
