My boyfriend went to his place for his birthday, and he let him stay there. Will you go or stay in a hotel?

Depends on how long you've been together. If it's longer, you can stay with him. After all, you are boyfriend and girlfriend. If you don't trust him for a long time, you can go to the hotel by yourself, but if you don't want to be with him. Then you can stay with him. Let him go out to stay in a hotel, or live with friends, because it is dangerous for a girl to go to a hotel alone.
