I agree, I'm sure he could find something he was interested in buying/doing online himself ... But somehow he can't find a therapist or ask via the gp?
I think you're right that someone with this attitude won't go if he can get away with it.
A man I was in a relationship with - also very verbally abusive incidentally - went to smoking cessation only because I searched for it and registered him for it; he was still smoking by the time I ended the relationship.
He thinks we should go together.
Why?
Are you calling him a fat bastard repeatedly during standard, relationship disagreements?
Did he end things with you before already due to you verbally abusing him?
He's trying to make out it's a joint two way problem. But it really doesn't sound like that.
You're "triggering" him - again it's pushing responsibility onto you for his inability to control his temper, and decision to start being verbally abusive.
He's blaming his stressful job too now .... excuses excuses.
Poor him - does he call his boss and work colleagues fat bitches/bastards when they annoy him or disagree with him?
Or is he saying he saves it all for his nearest and dearest because he represses his desire to call his boss/colleagues/customers nasty, abusive names and personal insults?
Lundy Bancroft refers to the "boiler pressure cooker" myth/excuse about male behaviour to cover their abuse. It's BS.
It would be useful to read his book if you haven't. It's primarily about physical abuse but applies to everything else as well.
