I think this is a good idea.

My T asked me this week why I tolerate some of the things my H does? I described on situation that came up this week. She said he was acting like a child. Why did you tolerate it? Would you have allowed your children to act like that. I said of course not. She was like why didn't you tell he was acting like a baby. I said I don't know I just walked away from him in the mall. I used to be very good at defending myself, but I am a total wimp now.

A self defense course would not help me much if our exchanges ever got physical, my H could squash me like a bug. I would however like to tap into that aggressive little kid once in a while.

I think you have been interested and focused on enhancing your communication skills. However, no matter how good of a communicator you are, your H sounds like a bully. Despite what the schools are promoting these days, sometimes the best way to deal with a bully is to fight back.
