B.C.
My wife and I have spent and saved together since we were married. Marriage was the committment. My wife's check is not her check. Its our check. My check is not my check. Its our check. My wife and I each have money we can spend for things, just because we want to. I use mine to buy vacations for us and presents for her and tools and other "man stuff". She uses her money to buy what she wants and I do my very best not to question her on the why's.
Buy a budget book. Write down everything you spend during a month. You'll be amazed at how much you spend on various things. At the end of the first month you and your finance should compare spending. If you are ready for the marriage comittment, then you will know it.
Cooking is not that hard. Can you follow simple instructions? If you can, you can cook. There are many 5 ingredient recipe books. When you eat out you are hiring a chef, a butler, a dishwasher and renting a dining room. Its expensive. You learned how to drive. You learned how to apply makeup. You learned how to do your job. If you went to college and passed any core class, or did any of those other things, you have enough smarts to learn to cook. What do you like to eat? Where do you go out to eat? Buy a cook book and follow the instructions. If you want others recipes that they like to cook go to an estate sale. Look through the cook books. When you find a recipe that is dirty and smudged, that's one the family liked. Buy the cook book, tear out the "dirty recipe", and throw the rest of the cook book away.
As far as savings go, pay your self first. My wife an I saved 10% per month, and that's with feeding an clothing 8 kids. After that, we spent the money that's left. We go out to eat once per week at the most. She and I cook well enough that we are kind of picky where we eat. If the chef at the restaurant can't cook better that I do I'd rather stay home and cook myself.
Good luck to you and yours.
