Have you ever been in a relationship where the other person harms themselves?

You always stand by her. You do your best to look out for her and protect her. Eventually she knows what she has to do to keep it at bay and will take those steps. It helps her immensely to know that someone has her back. Don't ever give up on her. Love her unconditionally. It's not an easy roads but she is worth it. Make sure she knows it.

No, but I was the one that harmed in the relationship. Knowing the why behind it helps and letting them know and feel like they can talk without being judged helps.
