My boyfriend has been acting very strange lady. He has been talking about god incessantly, continually almost insanely trying to draw closer to god, and his methods get weirder and weirder. Today he said that god was talking to him, telling him not to drink anything but water, but eating was ok. And he said god told him it was fasting. Should I distance myself from him? Is he becoming a fanatic? It's consuming his whole life and being and it's almost all he wants to talk about ever.
