It is admirable that you do still care about her welfare but it sounds like to me that you would be better off going your own direction as you cannot control her actions or stop her from moving where she is going to move. As far as her ex killing her, that is speculation and if I were you I would try to move on and take good care of your own self and stay positive if you can. This sounds like a guilt trip being put on you and you deserve better. You tried to help from a different state. You really don't know if what she says is true so please be easy on yourself and please don't feel responsible for her actions as you did not cause her to act the way she is or will act. Blessings and take care.
