Maybe telling him your not okay with his point of view on those type of things and that is an important quality to you. You just don't see anything coming from yall's relationship. (Also the guys who commented so far are kind of assholes) I think you're fine testing the waters with the guy before you tell him.
Your going to be wasting a lot of effort and time if this is going to be your approach into getting guys. I would tell him the truth or you can lie either way you come selfish and he'll probably think your an ass.
