I think I would let it slide only to a point because of BPD, but like I said there are some firm boundaries. Seems like all the time spent in Jail and Rehab she started to realize she has a problem, I've seen plenty of clarity moments where she would even admit she says "something is wrong with her brain" and many other times. So my last ditch effort would be if she agreed to counselling. Sometimes I think I might have enforced my boundary to hard and too quick without giving her an option. But then again I've been hit so many times in the past in her drunken/meth high rages I put my foot down immediately, not to mention my disappointment and upset mood took a few days to calm down. I don't feel I was in the wrong for enforcing it, I just look back and wish I gave her an option.
I only feel partially responsible for one thing. Me kicking her out for hitting me caused her such anxiety that she relapsed on meth/booze the same day. But at the end of the day she is responsible for those actions not me. I still feel bad though, especially knowing she's living
her parents where drugs and booze abound and it's only helping her slide further down the hole quicker.
Why don't I contact her? This is again my personal boundary. I do not want to give her the impression or feeling that I was in the wrong, and by my contacting her it will no doubt validate that feeling in her despite it being wrong.
