Hello Lynne & big welcome
can only echo what others have said - I understand how you are feeling been there twice although both daughters not married they have done the uni thing and now have moved away , although one is only 9 miles away it's not the same is it ? All I can say is you will come to love the calm , clean house !!
Like other wise ladies have said plunge in here and go to supper/lunch clubs they are a life saver and lots of ladies in same position as you
wishing you well and keep posting and chatting S X
