Even if you ask the question every night, no one can answer for him.
He might be thinking that if he wants sex with you too soon again, you might wonder about his true intentions. He may be trying to show you he really cares.
Just ask him.
he doesnt want to ruin it. he wants to make sure you and him want each other back before going to far. and if you find out you dont want to be together then you can be friends without it being weird.
