Just leave him alone! Sorry to say this but by you offering to just give it up to him, doesnt do anything but make him think worse of you and even if one day he decides to take up your offer, afterwards all that happens is you get more attached and he gets more of a mess on his plate. Dont do it to yourself, who is this guy? The massiah! Forget about it! He doesnt care about you dont lower yourself down just to get him to take advantage of you. If you do, in the end your just going to damage your own self image.
