Psychologically speaking I can't really give a valid opinion because of bias, transference, blah blah etc. However, I am familiar with her mental health history, and I didn't conduct those evaluations so they can be assumed to have some level of validity considering only certified and licensed professionals can make diagnoses. She does have Borderline Personality Disorder...and that has been a major part of our relationship. But I come from a family full of major mental disorders, practically all my friends have a diagnosable mental disorder...basically its one of the things that I could actually help her with and deal with because I had already been doing so for others for most of my life.

Borderline personality disorder is a condition in which people have long-term patterns of unstable or turbulent emotions, such as feelings about themselves and others.
These inner experiences often cause them to take impulsive actions and have chaotic relationships.
People with BPD are often uncertain about their identity. As a result, their interests and values may change rapidly.
People with BPD also tend to see things in terms of extremes, such as either all good or all bad. Their views of other people may change quickly. A person who is looked up to one day may be looked down on the next day. These suddenly shifting feelings often lead to intense and unstable relationships.
The outlook depends on how severe the condition is and whether the person is willing to accept help. With long-term talk therapy, the person will often gradually improve.
This could explain the entire situation alone. But nothing like this has happened before so idk. I think I might just have to move on...she won't find someone whos going to be as understanding of her mental state (unless her mental state changes) or be willing to deal with it (unless he is one hell of a guy) the way I did. Or maybe she will, who knows. Just need to continue getting my thoughts and feelings out to friends and family and qhimm forums lol.
EDIT: Thanks NFITC1. Your comment helped me to remember that she does in fact have BPD. And the reason I had forgotten was because our relationship had done a lot to (or so it seemed) "cure" her of many of the symptoms. It had been awhile since she had an episode...so it stands to reason that the first major episode after a long period of calm winds and still waters would occur in a way like it has. Started looking at other people's accounts of their relationships with BPD partners and they all say virtually the same things and the things they say nearly all apply to my current situation. I don't feel much better, but at least I have a perspective from which I can examine the situation where the data supports the hypothesis.
