Confuzed1,

Sorry for what you are going through. Lots of conflict is really stressful, and it sounds tough to be "diagnosed" with what you don't agree with. It sounds like you have already done some research, but check out this guide about BPD which could help clear things up?
BPD? How can I know?I am not a licensed professional. Personally, I believe only a licensed professional should give the diagnosis. I think you make an excellent point that anyone can exhibit the traits of BPD. I know I can. An actual diagnosis is complex.
I hope if what he is reading could be positive, it could help you guys cope with having high conflict, if it is useful as a general communication tool, but it sounds like you are maybe feeling accused of being responsible? For you personally, has the counseling been helpful at all? Has he brought up the BPD issue in counseling? Hang in there--others will chime in here to help you get a fuller picture. Glad you are here to get some support!
I did want to ask--I was unsure, are you saying you feel that you are not BPD but do have some of the traits, or do not have any of the traits?
