Thanks for the reply.
The only thing my therapist could suggest was to leave the room when he gets nasty to me.
It doesn't do any good to ask him to stop "whatever" because he responds that he's not "whatevering"

One of the things he's in denial about right now is that DD needs to take the medication that she's been described for bipolar. It will be 2 weeks tommorrow that we've had the prescription and he still deciding if he'll allow her to take it.

Yes, I do say things that trigger his behaviours. Everytime I ask him to do something- he blows up! It can be something as simple as put the silverware around, open a jar, etc.
Anything that wasn't his idea originally- is a really bad idea.

My mom's advice is to "not let it bother me' but don't know how to do that.
