Another thought...he may have mentioned it to his friend first because last time, you were less than receptive. Not to say there was anything wrong with your response. (I would have been the same way!) It just may have made him leery.
Maybe he didn't really want to go the restaurant, but had agreed because you were meeting friends. Maybe he'd rather stay home with you. Maybe he is just feeling tired because it's Friday. Who knows?? But, you're assuming.
Staying in the same place also means you're not moving backwards.
