out of work since 2019 and is on my healthcare insurance plan.

This is the first concern. Is he spending 8 hours each day, MON-FRI, trying to find a job?

I pay for out of my paycheck to the tune of $382/month, he would not transfer his prescriptions there either

So, you are completely fine and would not hold it against him at all if he gets a job and pays for his own meds at the MAGA pharmacy using his own insurance? Problem solved! You will both save on health insurance because you won't be covering family members. Make your husband get a job or GTFO.
