And his soul was drawn to Dinah the daughter of Jacob. He loved the young woman and spoke tenderly to her.
Genesis 34:3

Shechem "spoke to Dinah's heart," yet the heart is deceitful above all things. He manipulated her and lost everything for it, including his life.

Man's idea of "love" is define by how he feels at the moment. That kind of love is an illusion. If whatever you're doing feels like #love, but is contrary to #torah, it's a lie. It is not love. This is why we need Torah: to teach us how to love. God is love and all of his commandments are expressions of love and instruction on how to love.
