I have been in a relationship with my bf for 9 months. He is the most loving, caring, respectful man-when he is not in his 'lows'. We have wonderful times together, laugh together, enjoy each other to the fullest. We can have an amazing day-and out of nowhere he will go from being the happiest man to the most bitter, angry, depressed man I have ever met. The man I just enjoyed my day with will treat me like I am worthless, and threaten to leave for no reason. He expresses how he hates the world, and accuses me of things that make no sense. After a while, he is perfectly happy again-and a few minutes later-he is in a 'low' all over again. It continues for a while until I cry, or almost give up because I don't know what to do anymore, and then he is fine again, like nothing ever happened. I think he may be bipolar from my research and findings on other with similar stories I have read online. What can I do?
