you should play it cool. just try to keep the relationship alive no matter what. boyfriend/girlfriend, friend/friend...whatever just be nice and keep it alive. so long as you are keeping your emotions in check and are nice, boosting his ego - he'll seem like an asshole for doing anything mean.

on a side note - you do seem like you have low self esteem and suffer from very rigid thinking. i do not think this will be the last relationship for you - open up, put energy into your social life, give others a chance....
