Why are you confused? He's clearly spelt it out to you so re-read your own post and it will clarify things for you.
Now for my opinion: I think your relationship is toast so don't be hanging around waiting for him to come running back to you. He may come back but it will be for some familiar sex from someone he knows is still hung up on him and who is probably silly enough to give him uncommitted nukie... (that would be you, M325).
Learn a lesson from this and stop moving in with guys if your ultimate goal is marriage. You enable them to have to NOT marry you when you do that because they get what the need without the marriage when you're shacking up.
You're better off without him. If he's not ready to actually give you what you want with him then really, what is the point of keeping him in your life?
Beware of him coming back just to get a leg over while remaining uncommitted to you. If you have sex with him then you'll be also giving him no reason to even commit at all to you.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
