Hello ledz,
I first read your post not long after you'd posted it but I wanted to think about some of the things you'd said before I attempted a response. I don't know if you're still reading and I'm feeling a need to take a slightly different tack, nonetheless, here goes...

I am distraught . She had a manic occurance one week ago .today Sunday morning and the world turned upside down in an instant. The resulting outburst had me grabbing my things and leaving to the screams of "I hate you" and "I never want to see you again."... After one of the best and romantic nights we ever had, she now will not see me and talking to me gets her upset.

Obviously, you are far more aware of the history than I could be after reading just one post of yours and there is likely far more to the bigger picture than I could hope to see from my vantage point. Still, I wanted to note that what you describe above is not necessarily indicative of bipolar disorder even though there is evidence of a huge shift in polarities (she loves you/she hates you).

I should note that I'm new to the issue of sorting out what mania is so it's possible that's affecting my own perception. Based on the small snippet of your life together that you provided I don't feel confident saying, "That matches my perception of what I understand manic behavior to be." Just to be sure we're on the same page, I thought I'd share the following article excerpt which helped me to define and better understand what manic behavior looks like... (If I've sourced an inadequate quote I trust others will let me know.)

The above may be indicative of exactly what you have been seeing and experiencing with your girlfriend over the past several months. Or maybe not. You would certainly know better than I.

Part of the difficulty in making an accurate assessment is that depression + mania does not always = bipolar disorder. As but one example, I have a child who may have bipolar disorder because they have experienced both depression and mania, however the manic episodes seem to be closely related to recreational drug use and the depression may be related to a combination of life circumstances and choices they have made while under the influence of recreational drugs. Just because it looks like a duck and quacks like a duck doesn't always mean it's a duck.

In your girlfriend's case, her outburst the other morning could have been related to any number of causes. No matter, it is apparent that her behavior is impacting your relationship together and that is a problem.

The resulting outburst had me grabbing my things and leaving to the screams of "I hate you" and "I never want to see you again.".

I see this as a very positive move on your part, distressing as it may have been at the time. By leaving, you were sending a very clear message that you will not tolerate that kind of treatment. It could be that your girlfriend responded in that manner due to bipolar disorder, borderline personality disorder, unresolved trauma, drug use/abuse, fears of intimacy, or even because she learned that very behavior from her mother (who may or may not be bipolar). By walking out at that point you set a standard for your relationship that she will have to measure up to and no matter the cause, your willingness to insist on being treated decently may help both her and your relationship.

What I would suggest at this point -- take it or leave it as you see fit -- is that you focus first on your relationship. That might include learning skills such as how to fight fair or resolve conflicts. In the process, it may be discovered or realized that she brings one of the above to the table and she needs to tend to those details of her personal history and make-up. You might also discover that you contribute something unique to any problems that might spring up between you as well. You might find it helpful to seek out couples counseling in this regard. It might be helpful to seek out a therapist who also has some awareness of mood disorders so if that becomes confirmed, you'll already both be working with someone who can continue to serve as a form of professional support.

I would also suggest you continue to learn what you can about bipolar disorder, paying special attention to those who are actually in your shoes (i.e., either someone who does have that diagnosis or someone who is a partner to them). People that are closest to those in crisis can often be quite astute in their perceptions so it wouldn't hurt to familiarize yourself with the bipolar portrait but it's also good to remain open to other possibilities because it could be something else that's going on. No matter what that might be, her path will surely be made less difficult by the support and understanding of people who love her. In that vein, I can only offer my kudos that you do and that you're willing to do your best to stick it out with her.
