Would you be cool with your significant other staying the night at their friend’s house of the opposite sex?

So my boyfriend just called me insecure because I asked him why he think it would be cool for him to stay the night at his friend’s (a girl’s) house if he needed a place to stay while he was out of town. Am I wrong for feeling upset over this?
