Most Helpful Guy
Drop out as soon as possible if you want to be with a person who loves the real person within you and not with some maniac who just want to satisfy his urge and treat you as an object. I hope you understand how important is love over lust.

It depends on what you want out of it. If you're happy with just having casual sex and nothing more , just continue to see him.
If you're hoping it'll lead somewhere, and you're seeing him in the hope it'll develop into a committed relationship , then end it.
He's putting himself first by getting what he wants, so if you aren't getting what you want really, pursue a guy who is on the same page as you
