(((Marle)))
Lots of wise words above me. I do think you can have a relationship with her, but her behavior lately has been pretty good. It's not that out of the ordinary for someone who is ingesting all the drugs she is to act out in the manner she did. Like you said there is also still that part of her that is trying to 'test' you, to see how much she can get out of you, especially since things have been good.
Your doing good though!~ (and of course she still loves you)
Glad to see you keeping your serenity through this.
Much love and light.
