Extreme Views Hurting Relationship

Logically I know that this can't go on, but I would like some thoughts on my situation. My spouse and I have been together for 3 years. In the beginning of the relationship no conspiracy theories have been mentioned, but in the last year or so, they have become rampant. Everything from Blood drinking child killers, microwave causing radiation, elites controlling the world, symbols in everything, etc. - you name it, I've probably heard about it. Now we are hitting the point that he says that until I "conform" basically, I don't get the full relationship. Blames me for his issues.

The complicating factor is currently he is not working and doesn't have a penny to his name. He has all but admitted that he has a mental health problem, but he can't function well outside of our home, but obviously refuses treatment because "pharma" is in on everything.

I struggle with ending the relationship because he will become homeless. He cut off all his family as well.

Thoughts? Advice?
