Getting him educated and informed about Bipolar, what it does to a person, all about the roller coaster moods, the manic/depression, the meds that have side effects etc. Have him read book or look online. I really agree with all of the others that have said this. My husband just finished Bipolar for Dummies and I also read it and found it very informative for the both of us. It doesnt mean that you aren't going to have problems in your relationship because in my case my marriage has and is suffering all the time because of having bipolar, I think most people do. Someone can correct me if Im wrong here. Just talking personally myself.Good luck to you.
