Several years ago my H was like you describe yours, not wanting to go anywhere at all. I got so frustrated with it, that I finally just said to him one day, you can become a hermit if you want, but I LIKE going out and doing things so I will continue to ask you if you would like to go with me, but I will not sit at home any longer doing nothing.
The first few times he got a little miffed, but I would remind him of what was happening. Now he will go with me every so often, and when he doesn't and it doesn't interfear with anything at home I go without him.
Its just another way we have distanced ourselves from one another I think.
