Sounds like those controlling impulses are still alive and well.
I get what everyone is saying.
As for giving my H credit - he really is responsible for challenging my son in regards to food. At the end of the day I didn't have time. I was a single mom the first 8yr of a child on the spectrum.... I worked my arse off this with kid from the time he was 2yr old. 2-3hr of therapy a week which was 2hr drive... therapist 2-3 times a week. He did mainstream school without interventions which was a lot of work in itself. At the end of the day he ate 5 things... at least he ate something and only eating 5 things didn't keep him out of school. S19 will tell you that it was H... and it was a battle in the early years and I wrongly intervened (there are whys to that without going into details of his issues).
ANYWAY - doesn't really matter.
It just breaks your heart. I'm not the only parent who's partner walked out on them AND the kids. At least mine are adults now. Its just that S19 won't reach out because he's gutted and feels rejected. I'm not trying to control anyone save trying to control my kids pain AND that's the MOM in me.
I accept the benefits S19 got from H. I accept the loss that S19 feels at this time. NOTHING else for me to do.
