You're doing the right thing Hope! This is kind of what I was trying to spit out last night-don't lose sight of the forest and all that. Him having S meet OW--not the best parenting decision. Him talking to your S the way he speaks to you--that's something worth taking a stand over.
I would make sure you plainly tell your L details of his verbal abuse and intimidation towards you and towards your S. Maybe even print out some of your posts from here so you have specific incidences to elaborate on to give her an idea of what he's capable of.
You're not making things up. At this point, who cares what H thinks of you. You're doing this for your S--for him directly and for him to be able to have a happy, confident, strong mom and not see a woman beaten down by words.
