Be yourself. Don't force yourself to pretend someone you are not. If the guy is with you because he doesn't like you, but because he can use you as a living canvas for his fantasies and stereotypes, ditch him.
If you do want to adopt moe qualities, they're mostly about being weak, pitiful and silly in a cute and adorable way that embarrasses you/you feebly try to deny.
Give us more info to work with, will ya?
