My boyfriend and I have a son on the way and he was telling me basically if he too drunk to come home that he will crash with a friend and I said okay but I also asked him if that friend not going home but to their girlfriend house or a random chick his friend meet he said he would still crash there if he’s too drunk to drive cause he doesn’t want to risk losing his life trying to make it home drunk am I overthinking the whole situation?
