I love my kids dearly. but they will leave home one day. What will the relationship I'm left with be like. When I realized this, my husband became my first. It also makes "cutting the apron strings" a whole lot easier.
It is somewhat amazing what starts the demise of a relationship. You may never see it coming and it's something that no one ever mentions. Pay attention to the small aspects of life. The details tell you the quality or state of your relationship.
