I really appreciate your thoughts here. I hadn't considered the difference between mania and hypomania and will do some research right away. I am very hesitant to ask anyone that knows him for fear that I would betray confidence because I know that finding the medication and knowing about the suicide attempt have put me into a very small circle (and I don't know anyone else in the circle). While I am sure that his mania phase is high-functioning, would this mean that his depression may not be 'as low' (he attempted the suicide years ago during a self-described 'low' period and depression). I do absolutely know that he is either not medicated by choice or medicates only when the symptoms bother him.....(so not during the ups).

He broke up with me and has clearly stated that he 'fell out of love' (from deep love and total commitment for months to this stage in less than four days), so I am also not welcomed to pursue these answers. I would like the insight for two reasons ~ (1) for my own personal care of my own heart since I am feeling totally confused and devastated by this sudden shift and (2) understanding and preparation because, from everything that I have read on this site and others, his 'shift' may be short lived and I want to be knowledgeable should he change his mind again and reappear in my life.

I have left him alone entirely except to let him know that I care about him, don't blame him, and want to leave the door open to talk down the road.....in a letter immediately after he broke up with me. I will feel silly if I am completely wrong about this and learn that I've misread it. I don't think that I'm wrong about the bipolar, but just because he is bipolar doesn't mean that he can't actually have stopped having feelings ~ it's the suddenness of the 180 degree change and seeming complete lack of empathy that makes me think that it is something more than a normal 'boy dumps girl' scenario.

I do adore him and would like to be there for him as much as possible, but I haven't been invited to be anywhere near him right now. I would love your advice, though I understand that all of these facts are isolated and I may be completely off base with this set of thoughts (I don't think that I am, though). Anyone have advice? And, thank you so much for your help already.
