Men Like rules.
Tell him what you feel, how you feel and do as you please. If he doesn't like it, then he doesn't like you. A man would rather know how you feel , rather than have you spring it on him, in a cunning manner. Explain your requirements, if you feel he's worthy and it's not to soon to tell, then do it and let it be. After knowing where you stand, If he decides to exit the stage left, that's just his way of telling you that, he wasn't the one for you anyway.
"MEN LIKE RULES" They want to know where they stand, so let it be known. Time is everything, so do it in a timely fashion.
