I was wondering if there was something that you would really like to do in your life and haven't been able to because of children etc.?
Empty nests are hard to fill for a while I know..but I think we come to the realisation that it's now 'our' time to live
I think you have come to a crossroad in your life path...and that always makes life interesting..because now you have choices..I wish you well in yours.
Take good care.
