2.1 / (1 - 0.45) = 3.82 children per remaining woman, at equilibrium.
This only happens if you marry at, like, 22.
It's entirely reasonable though:
(38 - 22) / 3.8 = 4.2 years between children.
How much would that cost, though? To house them? To send them to college? Therein lies the difficulty.
Perhaps the solution is to simply accept that you will not have the money or the lifestyle you were raised to expect and desire. You will not have a big house, or a new kitchen, and you will not live in California. Your children will share a bedroom and have bunk beds. Your weekend plan will be to barbeque at the park.
It's doable, if you can find someone who wants to do that with you.
