I feel pretty insulted that I am apparently expected to be getting pregnant every year. I'm 25 and on my second!
Whoa, there! Hold on a mo', bumby! I think I've been misunderstood! The Church teaching is not "you must get pregnant every year unless you're so poor you can't afford potatoes." The Church teaching is: babies are good. Have them. But do have them sensibly. You go on to say:
Surely money is a huge factor? I cannot house more than two children right now, let alone ferry them about here, there and everywhere - we have no car.

About the spacing, I presumed it meant to space far enough apart so you can not have too many kids in your childbearing life - too many so that it means you can't care for them all adequately and foster their spiritual and emotional needs.
These are both excellent reasons to space your children. It's why I come from a family of three kids instead of twelve -- Mom felt she'd be a terrible mother of that many children, but, with God's grace, perhaps an okay mother of three. (She was quite good, in fact, if I do say so myself.) Both those reasons you've given are a long way away from spacing "just because." They're real, important, weighty, and serious reasons, and it is your responsibility as a married couple to decide whether it is a good idea to have another child at any given time.
I assumed the general idea was to be fruitful. If I don't use contraception, I don't see the problem. I promised to be open to receiving children from God. Nothing more.
That is the general idea. The concern is that there are couples who use NFP-based methods, not as a way of being fruitful (regulated in a natural, rational, economically and personally sensible way), but as a way of becoming barren for a very long period of time for entirely selfish reasons. The fact is, NFP-based methods make a damn good contraceptive (language intended) for those who choose to use them that way. And, according to the Church, that is not acceptable.
It's a subtle distinction, though, and you're twenty-five and already on your second baby. I think you're pretty obviously in good shape, and you obviously have weighty reasons to delay any more births for a long time to come (trusting in God's providence, of course), so I wouldn't worry about it too much. You're not on the wrong side of the Church teaching here. You're not even close. But it would still be wrong to prevent further births for no reason or "just because," which you are not doing, but that's the question you originally asked, so there's the answer.
I hope that was sufficiently disclaimed. I don't want to be thought some kind of Catholic baby-monger.
