[@Dawnscroll]. That's a real unlucky hand you've been dealt. I feel for you.

The good thing is that you've made your boundaries fairly clear. Whatever happens, just stick to them and don't be compromised or negotiated out of them. If you end up being worried about her, know that she has to be the one to change her behaviour if she wants to get herself out of her situation. You (and probably any therapist she's been seeing) have done everything that you need to from your end.

It sucks for a while, but the pain passes much faster than if you tried to chase after her. Take care of yourself.
