What Do Yo Think: Study Shows Unwed Parents Should Marry Before Child Turns 3
Here's my take: (No offense intended toward those who believe otherwise.) The willingness to marry the person you want to have a family with involves trust. Children need both a dad and a mom in their lives. And it's important for them to see what commitment to another person looks like.
I hate the line parents give their kids when they split up - "Honey, Mommy and Daddy still love you very much. And that will never change."
I think children need to see the love between their parents before they can truly believe that.
