Husband only wants 2 children

I want to have 3 kids and he only wants to have 2. It makes me so sad because i love kids and i want a big family with lots of entertaining kids to make me smile everyday and enjoy! I like busy schedules and having things to do and i think 3 kids would be perfect, iv always dreamed about 3 children and how that would make the perfect family in my opinion on the other hand my husband only wants 2, he says kids are expensive and doesnt know if we would be anle to afford 3 kids and he likes peace and quiet sometimes and thinks 3 would be too many to keep up with. Im a stay at home mom, and i do most of the work taking care of them, he just works to provide and thats great, hes a great daddy, we have one child now and trying for our second, really trying to talk him into 3 so hes ready, i want them close in age. Im not sure what to do, hes pretty set on 2 and im determined to have 3! what can i do? how can i talk him into it? how do we compromise this?
