God, it sounds soooo disloyal but I am generally not disloyal to him
Love, that is not disloyal. Grief, regrets, anger...they are are not only perfectly normal responses, but responses (to the profound changes you are BOTH going through) that really shouldn't be without an outlet.
We are responsible for MIL who is physically and mentally disabled, (which I appreciate is not the same level of struggle you are dealing with, there are far more layers when it is your spouse or your child who needs your care) and I would go stark raving mad if anybody suggested I wasn't allowed to feel the disappointments, the anger, the sense of being trapped, the regret and a whole host of other unpleasant emotions that can go with that reality.
In retrospect I wish we had gone in for some sort of counseling when things reached a point where it really changed our lives. But time did help as we got more used to the new reality and started to be able to see things we could jig about to make it easier to live with. What looked like being at the bottom of a dark pit turned out to be more of a tunnel, with light at the end. Although I find it is rather like driving through the mountains, you come out of one tunnel and spend some time in the sunshine, but there are new tunnels up ahead to get through. It's just they aren't as bad as the first one, when it was all so new and scary and I thought I was in a pit.
What I am trying to say is that YOU are entitled to feel the loss that YOU have suffered as well.
Do you have any sympathetic ears or shoulders available in RL ? Friends or family maybe ? Because having a place to vent and unload to stop stuff festering or getting volcanic from suppression can be a real help.
Does your husband's specialist know of any support groups for younger people dealing with his condition ? It might help him in the journey of coming to terms with things if he could unload onto people who totally understand what is going through his head and maybe even open up a new network that could lead to more opportunities over and above the TV. Which might take a good lump of pressure off you too.
School could be a good idea to help your DS make new links in the new area, I'm fairly certain that if we moved (fat chance with this market) I'd have to send DS back to school (in the short terms at least if we started having the same problems we've had here) to establish him in the community. I have traded so heavily on his school friend network to get him the sort of social life he needs\wants and it wasn't easy even with those connections in place.
Not sure it would have been that successful if we had come in "cold" to a place because he tends to make new friends via existing friends. He has always been pretty good at making friends from scratch when entering a new school, but less willing to entertain the idea of going into a social\sporty environment full of kids he doesn't know. It might be easier to sell the idea of a return to school "for now, while we adjust to our new home" rather than "forever" if he doesn't seem so keen on the idea and then revisit how permanent to make it once you both have had a chance to get a good idea of what it is like and how happy he is with it.
