The most obvious example of heartbreak is the loss experienced by the death of a loved one, but there are other kinds - the loss of love in a relationship, the hurt experienced after the action of a friend, the blameless loss experienced when a loved one moves away (or goes to college). We hurt - our heart hurts.
"To love with any level of intensity and honesty is to become vulnerable."
When I was dating Steve, Mom said, "I just don't want you to be hurt." I told her I knew I could be hurt, but I was willing to risk it anyway. And because I did, I have experienced the greatest joys of my life - my relationship with my husband, the gift of my children.
Do we avoid heartbreak by avoiding love? God has made us to love others, and it is that very love that makes us vulnerable to heartbreak. The only way to protect ourselves from heartbreak is to keep our hearts to ourselves, and to not love others. It's not an acceptable trade.
