Is Pretending To Love Someone Sinful?

In this episode, Dr. Betters answers the question, "We are supposed to “love” our neighbors and our enemies but I just don’t know how. I have had some people in my life that have really hurt me, broken my heart and betrayed me - how am I supposed to love them? When I shared this with my pastor, he basically told me I needed to “fake it till I make it.” Are we ever supposed to “fake” loving something? Isn’t pretending to love someone just as sinful?"
