Of course you want to get married, have a baby, because you have nothing else to do. Now you are totally dependent of him, you have no other interest and that's make you think that he is the universe. 逼他結婚? What's happiness will you have if you have to force him?
生BB? Don't even think about it unless you are financially secured.
定係聽他講? I think he is right not to get married at this stage. But unfortunately you need to have an id card to get work. Talk to him. Tell him that you really need to work. Either get married and get a job in HK or go to mainland to work. If you really love each other you should trust each other, a little seperation may be good for you before you get married.
24 is too young to get married, you haven't really faced the world yet.
