Do not let him off that easy, Irish. Give him a day or so to cool off, if need be, but keep on target with the therapy. And don't allow him to turn it into an argument.
Easier said than done, I know.
I agree with Rob that you need to figure out just what you want to do and to understand the consequences that will come of however an ultimatum might turn out. And if an ultimatum about the therapy is indeed what you really want, then proceed with that.
I guess what I am trying to say is that at some point sooner or later you must tell him what the consequences of his recalcitrance on these matters you hold dear will mean to both you and your M. Your H is going to have to either face these issues with you and with the help of a therapist ...or all by himself after he's destroyed his life.
