My husband thinks that autism is an excuse for attention.

Married 3 years to a good guy but he thinks I spoil my son when I visit him 1 or 2 times a week. I teach him to cook, bake, do laundry and wash up in his appartment. What am i doing wrong? My husband is not my son's father (he died). How can someone not understand that i love my son and want to help him be self sufficient. I'm not a psychiatrist so i can't help him in that area. But i can love and support and encourage my son. I don't understand how this nice person doesn't get it.
