Stay at the hotel with your boyfriend.

I think he has proved his promise with his actions. He told you to stay with him, and he wouldn't touch you. He suppressed a man's desire for you, and he did it. He doesn't want to touch you before the wedding, because he knows he has a responsibility to you. He is a person who cherishes you, restrains his desire for you and keeps his promise to you. I think he deserves your trust.
