Hello determined 1,
It sounds like you are feeling frustrated by your GF's behavior. It is commendable you took the time and cared enough to try and find out why she is behaving the way she is. When I found the connection to BPD and my ex it was 2 months after she discarded me. I wish I had had the presence of mind to see that there was something deeper going on with her long before that happened.
What behavior have you noticed that leads you to believe she suffers from BPD? There are a couple of articles on this site that can help answers some questions you might be having.
Is it Borderline Personality Disorder?DSM Definition: Borderline Personality DisorderConfronting someone with the knowledge you have gained can be difficult road to travel. It generally won't be received well as you have discovered.
Based on her deflecting it one might conclude that she is aware there is something wrong but can't quite find a way to accept it. Would you say this is true?
As you might already know there is no cure for BPD. At best it can be managed with dedication, hard work and sustained effort on her part. It will also require a lot of love, patience and understanding on your part. You will need strong boundaries and emotional strength to endure the dysfunction you may be dealing with. Have you had a chance to read any of the articles and lessons on communication that are in the box on the right side of the page?
