I’m a mom and I’m divorced, so…take my advice FWIW.
It may seem that your H is doing more of the fun stuff, but as others have said, there’s a place for fun stuff. Remember that if you end up divorced, things will get worse for all of you.
I heartily endorse the support group idea. Maybe your H would come too. It might help if he met some other dads in the same boat.
Personally, it sounds to me as if you could use some more paid help. My D hated to write…just hated it. We’d fight like crazy. I finally hired a teacher to tutor her, so she’d fight with the tutor instead of me. She did fight with the tutor—whom she’d really liked before the tutoring sessions, but my D and I spent a lot less of our limited time together arguing. I don’t know how much of the skill set stuff for S1 can be handed off to a tutor, but I think you should try to shift some–preferably to your working hours.( Hey, on CC there are parents who admit they hired a private college counselor primarily so somebody else would do the nagging.)
I was much closer to my dad than my mom. Dad never tossed me a ball. He didn’t teach me to swim or ride a bike. Why? He didn’t enjoy doing these things. Does your H like to toss a ball, ride a bike, swim? If not, I wouldn’t push your H to do these things with his sons.
What DOES he like to do? Does he like to play board games? There are games, e.g.,Sorry, that your sons are old eough to play that dad might enjoy playing with them. Even card games like “Go Fish” or “War” can be fun. Maybe this book would give you some ideas. http://www.amazon.com/Activities-Children-Aspergers-Processing-Disorders/dp/0071623361 My dad taught me how to play cribbage because he enjoyed that. Would he enjoy reading to the boys? Does he like music? Does he play an instrument? He might teach his sons how to read music. Does he like to garden or would he enjoy learning how to? Planting some veggies together might be a good activity.
Then there are classes in the community. Maybe your H needs some help. The married D of a friend discovered that Home Depot offers parent-kids classes. I just checked on-line. They are free and offered the first Saturday of every month. The classes are for kids 5-12. http://workshops.homedepot.com/workshops/kids-workshops The parent and child learn to use tools and work on a project together. Home Depot instructors lead the class. Her H really enjoys doing this with his S. (S is now 6; they’ve been doing this about a year.) I don’t know if S1’s issues would make this impossible, but maybe he could try it with S2–who may need some attention.
Googling turned up this. Again, I don’t know if your S’s issues make this suitable or not:
Again, half the fun of something like this is meeting other families in the same boat.
I didn’t deal with the issues you’re dealing with, so on that score, I can’t be much help. But if you want him to stay with your family, let him have some fun. It sounds like spending more time with the family is a new experience for him. Let him enjoy it to the extent possible, especially in the beginning. I think you need to have more fun with your family too. So, do try to pass off some of the drudgery stuff to paid help.
