… sounds like she wants to stay and be single, change in behaviour?
When a child comes into the picture, this generally shifts a persons priorities. This is not a "BPD" thing. She hasn't physically recovered from the birth, the child is fully demanding her time and disrupting her sleep… how practical is dating at this time?
Jammo, you have to start detaching. The cyberstalking is not healthy at this point. You keep trying to get into her mind from a distance, looking for a way back in.
If you want to rekindle the relationship, this is not the way to do it. If the two of you get back, you will likely repeat the same mistakes as nothing has changed with you.
If you want to move on for your own sake, this is not helping. Your focus is and has been entirely on her - you are barely looking at yourself at all here. You know more about here psychological makeup than your own.
Your not on a good path right now. I'd give some thoughts to shifting the way you are processing all of this on a day to day basis.
