Dont,

My wife has bi-polar(type 2 rapid cycling). OCD, BPD, agoraphobia, bulimia. My daughter and I recently went through NAMI's (National Alliance of Mental Illness) family-to-family course. It has helped me tremendously to empathize with what my wife is going through. She did not ask to have a brain illness. I am in it for the duration. Maybe you need to ask your SO if he is? If so, I cannot recommend this course enough. See if it is available in your area. Check out their website. It has lots of good info.

All the best.
