(((HUGS))) - I think it hurts when a couple splits up even when they both agree its for the best because there is still a part of them that wanted it to work out, that wanted to be loved and wanted to love another in return.
Please be gentle with your self in the coming weeks..... take time to cry, but then relax and let your mind go far away from the marriage that is over so YOU can be placed back together --feeling better as the weeks and months pass.
