Your husband sounds like he is struggling trying to adapt to your new address. I can understand this as I've just moved again and it's so much harder each time I've moved house. I also think it gets harder as we age. I grieve for what I've lost each time I move. Many people over look this fact as moving house and the adjustments required take their toll on us.
He could be missing people, his house, job, garden or a number of things.. Its like a type of grieving for me & with each house move I've made its a new grieving I need to go through.
Your husband sounds like he's going through something internally and hopefully this will sort itself out in time.
Has he got any interests of his own? Other than counselling (which he may not want to do), is he getting enough sleep also?
I know it must be difficult for you as you would feel helpless, just look after yourself... xx
