My husband

New member here! My husband has been Diagnosed with bipolar he 4 months ago. He was the perfect spouse, we were best friends- laugh together, play games together, watched movies together, did crafts together and all of a sudden he fell into a politic driven spiral addiction that now has led him into believing that he is now the chosen one and that crypto currency is going to be the way of the world. I am not sure what to do with this point in convincing him that the stars do not move, their are not lights in the woods, that people know things around him and are in on some conspiracy. He has not been working for 4 months (he has a Dr degree), spending a ton of money, agitated all the time and isn't the person he once was. Pleasr help
