Hello uncertain,
Welcome to healingwell and the bipolar forum.
I'm sure this situation is very confusing for you right now. I think you should definitely put your plans on hold until you both have a full understanding of what is going on.
I would suggest to just being supportive, and make sure you both understand all that is going on. I would suggest that you go to his doctor appointments with him so that you and he both understand all that is taking place, what they think is going on and what they decide is going to be their treatment plan.
Be prepared to ask as many questions as possible, until you feel you truly understand things.
If he is diagnosed with bipolar, things can get worse, especially if he is incompliant with taking his medications properly. Being diagnosed with bipolar (if that is what is truly happening) can be a long road to wellness. It takes time to find the right medication balance, but in order to find that means you go through the process of living with symptoms that may not be pleasant for either one of you.
Take one step at a time right now. Listen carefully to what the doctor is saying. Is he seeing a psychiatrist? That is the type of doctor who should be making a diagnosis of bipolar.
But definitely keep things on hold, until you both know what you are dealing with. You shouldn't be making huge decisions right now when so much stress is involved. He needs to take care of his health issue at the moment.
Good Luck. Continue to post. We're here to help in any way we can.
Sincerely, Sukay
