Dear Nik...I get where you are, I been there, not with a spouse...with my Mom. It will be many emotions overwhelming you, and no matter how much you would have tried to prepared, it would still be tough.
I was also, wanting to accept one place for Mom to reside, and was both glad and sad, when she was accepted.

It is gonna be alright...lots here saying prayers for all of you. The doggies maybe can visit some days.....all will fall into it's proper place.
