Where Our Heart and Mind Take Us in Love

I read an expression recently. It said, “We fall in love with our heart, we fall out of love with our head.” When I think about this I know it makes a lot of sense.
I have this friend who is sad that her marriage is ending. She still loves her mate, and she is feeling what her love is creating from her heart. She thinks about the good things that they shared, before things got bad and drove them to divorce.
