Story, if there is one thing I feel bad about with my single parent mother is that I never saw her cry. She lost her beloved husband, she worked hard and raised 3 children and had my grand father come live with us the year before he died...and I know she must have cried. I wish I had been a wiser child and encouraged her to share her feelings instead of hiding her sadness.
Your children will learn so much from you, more than most children learn in a 2 parent family. They are a gift, life is a gift and I am glad yours is happier today.
Hugs
