With Leah, I'm going through a similar situation with my best friend. I tried everything even asking her the hard questions and I told I'm not removing my dislike for boyfriend. He's emotionally abusive, a liar, and very manipulative. I understand what you are going through. Ask Leah the hard questions. Give her something to think about. then if you believe in a God or Goddess get that divine intervention going.

Hard questions to ask:

Are you positive it's not physical attraction you are confusing with love?

Those will getting her thinking. They are seed questions they'll scream at her after he does something to her.
