A Narcissist can show fake affection. It's not genuine. It's only for their own gain. Don't fall for it. Be respectful and learn to love from a distance, if you don't want to get hurt again. They can't help themselves. Unless they're in therapy multiple times per week for NPD, there's just no hope for them. Do you really want to live the rest of your life this way? That's the million dollar question.
