hh, your husband is an abusive man--never forget that. I wouldn't give him a speech at all--at least not until you are safely gone.
I know I sound like a broken record, but please consult with a DV advocate about how to do this safely. Abusers do NOT take kindly to being "left." THEY want to call the shots, and your leaving is a direct challenge to his authority, from his perspective. It can be VERY dangerous, even if there hasn't been serious violence in the past.
Please call. It doesn't cost anything, and you don't have to take any suggestions you don't want to. The ball is in your court, but it only makes sense to consider all the angles.
