listen to him carefully, and re-cap what he says so you know you are understanding him, not reacting in fear or lashing out.
You do not need to decide or agree with him on everything. You are allowed to say you will need time to process things.
True, you just told him you wanted a decision, but I doubt he'll press you for a response immediately. Regardless, you do Not NEED to answer him with a ready reaction --- and being angry will absolutely not help you.
Do you believe your conversation tonight needs to be better than today's? If so, act accordingly.
Just hear him out.
