I think you express how I anticipate feeling should myself and partner return.
There is a possibility my husband may be offered worked back in the uk (I would need to remain in Oz for the time being).
Both our kids would remain as the youngest (18 year old) is moving interstate to study and the oldest (22 year old) is finishing post grad study and will most likely moved interstate for work. So we would be without them wherever we are.
However I’m very conflicted about how I feel about a possible return for us both.
