Oh man.
My heart is truly breaking for you. I had to rehome 2 of my dogs when my mom became disabled and we lost our house. it is truly a heartbreaking experience. I still get teary when I think about it, and it's been 2 1/2 years.
Perhaps you could find a YT member in your area who could foster him for you. I know you said your family can't. Try posting in the regional forum! I would suggest that you still visit him as often as possible, so he retains the full memory of you (that way it won't traumatize him more when he goes back to living with you).
I really, truly wish you the best of luck. I'll have you in my thoughts and prayers.
