Hi Sister Rags, firstly kudos to you for recognizing you need medication, recognizing it's nothing to be "ashamed" of, and sticking with it!!!
Now the "intelligent man" bit I'd really like to dispute but.........
If he's religious (the "Godly" comments) there are plenty of religious people out there who do "get" mental health problems and the neurobiological aspect, do you think gathering their opinions might help convince him just a little?
Even if he goes to any church would there be anyone there, if you check it out, who could talk to him a bit more about the real side to it. Or if it comes to it even things you can find on YouTube with the combined spirituality and mental illness aspect agreeing?? Then he may be more "enlightened" about not only your situation but (long shot!) his too.
Otherwise if you could just agree with him that this is your choice for you, non-negotiable, and an agree to dis-agree aspect of your relationship.
But you know, if nothing's worked/working I'd seriously be suggesting you "show him the door". You need far more understanding than that!! And with an attitude like that what I'm reading is going to be "the tip of the iceberg", right? If he doesn't get the causes, that it isn't your "fault" then he isn't really getting the rest of what you are dealing with, right? He isn't really going to be offering you real support when you need it? Maybe even making things worse for you?
But you know the situation far better than me, just something to think about???? And here's hoping you're getting great support from a pdoc.
