The near enemy of love is attachment. Attachment masquerades as love. It says, “I will love this person because I need them.” Or, “I’ll love you if you’ll love me back. I’ll love you, but only if you will be the way I want.” This isn’t love at all - it is attachment - and attachment is rigid, it is very different from love.
