Do you think that it would hurt a guy if you tell him this?

"Although I appreciate your care for me, alot of your actions have not materialized in real life. Since we're not dating, I hope you'll appreciate that I will be free to be on the lookout for other guys while I know you because you're not my boyfriend. And you can do the same too. If either of us find somebody who we want to marry, let's just keep it at that. That's what I really hope would happen right now."
