Glad you are posting. You found a great place for support. I have been reading and watching here for about 2 years now. I have seen what works and what doesn't.
You have a choice between reacting or responding to him. I strongly suggest responding with guidance from people on this website.
Initially, I would suggest responding to anything he asks with:
"I will need time to think about that. I will get back to you when I have decided."
