His personality is so strong - how can I assert myself?

Question

I am rather shy and an introvert.
He has a very strong personality and doesn't really mean to be controlling but he just takes over.
And he will notice it, and say "OK, you carry the conversation" but I feel put on the spot and draw a blank. I feel so stupid at that point.
There is so much I want to talk about but I just feel overwhelmed.

Answer 1

Just take a deep breath and do it. Force yourself to do it. It will be hard at first, but will get easier with time.

Answer 2

It may be that you should just say goodbye. Controlling people only get worse usually.
