As one who is there(married to a person with bp) I will say it can be tough. Relationships are always tough, but throw this in and "WHAM!" I think/know a lot of time people don't truly understand the disorder(s), don't understand what they need to do or can do to help(that helpless feeling is awful!), and are not strong enough or brave enough to leave the relationship if they cannot live with it. So instead they try to deny or wish it away. I know I am a very strong person emotionally/psychologically and my wife's bipolar darn near destroyed me before we began to get some semblance of control. My life revolves around work and helping her manage bipolar now with very little if any time for me. Oh, and battling to keep from becoming co-dependent myself!

Tell your sig. other how it is, this is what I have, this is what I need from you, you can either live with it or not. Not something you can really candy-coat.
Hope it works out for you whichever way is right!
