I really like the Star Wars universe. Trash and all. Could Disney do better? Yes. Could Lucas Arts have done better? Absolutely. Art is never perfect, but that is what makes the art beautiful. Perfection is boring.
But as someone who used to despise Star Wars, you really need to pay attention to the extended universe(EU) to get a more complete picture. The EU fills in all the holes that the movies/shows create, provide a better view of what the force actually is, and often provides more interesting stories by not focusing on the Skywalker saga.
I now absolutely love Star Wars only because I gave the EU a chance.
Not a financial advisor so take my answer with a massive chunk of salt.
My suggestion would be to get a joint account. If you are comfortable paying all the bills you can also have it overdraft to your account in case of emergencies. The move money into it monthly for bills. I would round up on your bills so you could build a little nest egg at the same time. You move everything that you have been paying into it. And ask her to move what she can into it. If she feels comfortable paying 50%, then do that. If things go sideways, split any extra money by the percentage she is paying. Then if things do go sideways then you can take your piece and have a nice vacation. If they don’t, you have nice rainy day fund.
