What do you do when you find out your boyfriend still believes in Santa Claus?

Believing in Santa clause has nothing to do with relationships directly, however the mentality of childishness counts, that means it depends on the belief he has. If he only believes and doesn't like worship Santa then it might even be nice for your relationship as it is that he might make you laugh on those days when people are celebrating the Christmas season. Everyone believes in something but the degree matters. For example if he so much believes in Santa that when you talk bad about him he doesn't eat your food then something is wrong and he needs help through counseling and therapy, but if he jokes about it and his believe has not negative effect on your relationship the i guess its okay don't take it harsh on him because many of us grew up being told stories of Santa clause and they are still fresh in our minds we do celebrate Santa in the Christmas seasons.
