Do you regularly have meetings where you talk about goals? If so, that would be an ideal time to bring it up. Even if you don't, try scheduling one. Talk about the freedoms a higher income would provide. Retirement, college, emergency savings, fun money.
What does she do now that she wouldn't be able to do if she worked more? Would outsourcing housework help? Would setting up a recurring ladies' night help her feel like she will be able to remain social?
It's hard to have coffee after school drop off, squeeze in yoga and lunch while working full time. I can see why she won't give that up readily for some nebulous goals.
OP, since she has ceded the financial reigns to you, put her on a tight allowance -- basically saying most of money is spoken for Tsp 529s etc. I would setup automatic transfers, eliminate all credit cards, and give her one debit card which is tied to the account her allowance is deposited to.
If she really is feigning ignorance or can't grasp these things this is a prudent approach and ensures the needs of the family are met first.
