I’m really nervous🥺

This guy I’ve been talking to for a little bit invited me over to watch a movie. I trust him and I know he wouldn’t do anything that I didn’t want and I want to go over it’s just that I’m REALLY nervous. I’ve never been over a guys house and I don’t know how to act or what to do. PLEASE HELP ME! my anxiety is through the roof right now and he wants me to come over tomorrow.
