Hi Randomuser94
What you need to realise is that a pwBPD relies on their feelings to make decisions. Feelings constantly change so what they want will always change. When it comes to you depending how she is feeling will decide what she wants. This can chop and change constantly throughout the day.
She may decide that it is you that she wants. If she does and you get back together you have to be prepared for her feelings to change again.
What bothers me is that I know the game she's playing and I got tired to play by her rules as the result is always the same.
