Living with boyfriend, no commitment yet

I'm 25 years old and have been dating an amazing guy (also 25) for 6 and a half years. We moved in together a few months ago (when our jobs made it more convenient) and he is aware that I'd prefer to be committed. I thought he was going to propose beforehand but I know now that he hasn't even thought about a ring yet. We talk about marriage and he sees it happening sometime in the future but I think we have very different timelines in mind. I wonder if I should move out or continue to wait patiently. We love living together and are amazingly happy but I'd prefer not to play house before the real thing. Moving out would be a huge hassle and I definitely don't want the relationship to end but if things stay as they are I'm afraid my unsubtle hinting will ruin the relationship and I will start to resent him for not being as ready as me. And if I move out will I slow things down even further...

What do you want out of marriage that you don't have now? What does he want? I think that marriage may be a quick step to divorce if the two of you do not want the same thing. I think you need to get this clear.
