OK, I know this is a guy's perspective, but I would personally let him go. He's not going to get assimilated for one night, and it sounds like you could use the "quiet time". Play the music you want to listen to, sip a glass of wine, and relax. And, if you start feeling guilty, picture the scene of him asking all those questions out loud in the hall!!!! then you'll be LOL...
