Your husband is probably waiting up for you...

You should go back. You know your husband wants you to have a good time and enjoy your night off, and you have. Now you can go back and tell him you had fun, and then reconnect with him. Maybe show him how much you appreciated the break from your daily life this evening. You tell Pierre you've had a wonderful time, but need to leave. He, ever the gentleman, is completely understanding and offers you a ride home.
