She referred to the family home as 'I am at home with the boys at the moment'.
Perhaps you are right in that she must start to think that she could lose something. When I contacted an old female friend it did seem to shake her - she did admit to doing a lot of crying at the time.
Perhaps I should do more with the boys outside the home - but not ask her to join us, to see that we are doing things without her and that we don't need her....
Cause all of the stars, Have faded away, Just try not to worry, You'll see them someday. Take what you need, And be on your way and, Stop crying your heart out.
