Hi kjohnson
I am sorry that your hubby is in denial. Has he actually been diagnosed with bipolar? I burned out of my career and ended up in a psych ward and came to get diagnosed with depression and I had to accept it as I came out of the hospital pretty much slurring my speech from psych meds. I was later misdiagnosed with bipolar and I was already pronounced depressed so it wasn't so much a hard thing to accept the bipolar diagnosis. I am still not sure if I have bipolar as my case is not typical.
Not sure if you can force anyone to accept something that they are not ready to accept. You might be fighting a battle that you cannot win. Maybe you can start some counseling sessions for yourself and then get him involved.
Just a suggestion. I hope this helps in some small way.
