I feel insane after trying to convince several MH professionals that my husband is bipolar

Husband had first psychosis due to stimulant use for ADHD and cannabis (also had CHS episodes) in 2020: I reached out to his psychiatrist and she removed stimulants and got him on benzos, but no bipolar diagnosis was discussed.

Years later he was on stimulants again, then later cannabis. Affair, discard, wracked up 50k in debt, I told his therapist that he disclosed to me he thought he was bipolar… nothing.

A few months ago he had his first in patient hospitalization. Gave up cannabis and got off stimulants. He kept telling everyone in the hospital he was there for addiction to cannabis, then even “dopamine addiction”, the psych got him on quetiapine and no more stimulants. He’s been on them consistently for 8 weeks but… despite me telling the psych during a meeting about his past psychosis, delusions, etc, his next follow up appt is in SEPTEMBER and he again left the hospital voluntarily without his diagnosis. They just sent him home to me and our children without any follow up. I felt insane, that the meeting with his psych was to humour me. He had an appt in hospital with the psych prior to mine, and my husband seemed nervous and weird the entire time. Just a distinct feeling as if he had already been like “my wife is going to say I’m crazy so just humour her”. The psych spoke over me, hardly listened and kept the discussion all very sparse.

He convinces his family it was just a cannabis addiction. He convinces doctors and therapists that I am controlling and act too much like a caregiver.

Is it truly possible that no professional will ever see that he’s bipolar? I understand he’s only showing this side to me, he can be charming, he is good at minimizing and downplaying, and can even convince others I’m abusive, paranoid, controlling, etc.

His new outlook is that I’m a narcissist and feel entitled to always be right. He calls me a victim, tells me that I want everyone to bend to my will, etc. He completely evades in person or virtual therapy and won’t return to his therapist or consider couples counselling.
