The AS ex is in bits at present as his eldest is seriously ill overseas. It's just insulting to call him uncaring when he's been running himself ragged for months to try and help the lad, (literally hopping on and off a plane to come to the UK, raise the funds, take cash and get back on a plane & then do it over).
I'm sure you'll understand here just what an emotional toll the constant country hopping is having on the poor man. All those changes and transitions.
Not many NT Dad's could or would go to the lengths he has the last few months, & after his support last year for DS I'm of the firm opinion that the AS Dad is the Dad to have your back in a real crisis - just don't expect him to discuss Eastenders with you, or endure the caring carrots. (Bit sad really cos years after our split he starts reminding me why I ever fell in love with him in the first place).
Being uncaring has fook all to do with AS/ASD, if any stereotype is appropriate it's more along the lines of it being too damn easy for the NT bitch wife to take advantage of the AS hubby sometimes. Some of those posts, if read by the spouse are so insulting that the smug bints deserve to be divorced as a result.
When the crisis with his eldest is resolved DS & his Dad are off to tour a commercial bee-keeping facility together. Gotta love those obsessions
