OP I could have written your post. I'm following with interest as I don't know how long I can do this for.
DH and DS are both undiagnosed. DH isn't interested but anyone who has met him agrees he has ASD. DS is on the pathway for assessment.
The management of our lives is exhausting. All admin falls to me.
Left to him DS wouldn't be getting any help, we'd never leave the house, DS would be on screens 12 hours a day.
DH knows his role and what his jobs are. He likes the boundaries so I always know where he is, and never have to nag.
He never minds if I go away for a weekend, and I do this as often as I can because I need to decompress. While I'm away I make suggestions for things they can do, so I'm still managing them. He's a fussy eater who can't cook. DS will eat anything and I'm determined to teach him to cook when he's older.
He isn't great with admin unless I specifically give him a task, and these will often be left undone because he doesn't know what to do.
I delegate all I can to him but still have to check.
I long for spontaneity and someone to laugh with. Affection is always going through the motions. He kisses me at the start and end of each day. I have to ask for more.
He's totally introverted and doesn't chat. I outsource my social interactions which went out of the window in the pandemic.
For those wondering why I stayed with him, we always had lots in common to begin with or so it seemed. As the years have gone by, he masks much less than he did at first.
