Here's a question for you.., how sad would the world be if the only great proclamation of love was marriage and nothing else? To limit oneself and one's own love and happiness to the confines of what makes a decent marriage? It sounds as if you're asking for disaster before it even begins.

You should want him to want to marry you, and to want to marry you when he's ready. Not because you're essentially putting an ultimatum upon him. It sounds like, through your own words, he's doing things right and giving you just about everything you need to have a healthy relationship. You're now sabotaging it because you failed to express your own beliefs about marriage up front. If this is how you really felt than that should have been your lead. "I expect marriage." Not "how do you feel About marriage?" As if it's an open discussion, Then get upset it doesn't match your own feelings.
