sorry to hear bout this TS..

seems like u both rushed into a relationship without getting to know each other..

it does seems like its all bout sex..
but at least he didnt just bailed after u both did it...

mayb u could try to find out whether he be with you is just for sex or more than that..
try not to have sex with him for a while.. make up some believable excuse or avoid going to his house.. and see whats his response..

If he's still ok with it then i guess it's still rescueable..
if he stop asking you out when he knew he;s not gonna get lucky that night.. then u know whats his motive...
