The adage, "save your money for a rainy day," could not be more true in this day and age. It becomes even more apparent when you get married. You now have two checking accounts to manage, two credit history's to partner, and you take on each other's debts.
I found a great article from The Fiscal Femme who also writes about many other ways to save, invest, and retire with your money! Finances are definitely never an easy subject to talk about, especially if you have a lot of baggage (read: student loans, credit card debts- were the shoes worth it?). The most important thing she mentions is honesty.
When you're talking with your fiancé about your finances, be an open book. No sense in hiding it as he or she will soon find out if your a financially stable partner. My advice is to to begin talking about finances as soon as you are in a long-term, committed relationship. It's 2014, men don't always have to pay for dinner or take you out. You are a strong, successful and confident woman (or man!), own that, be proud if you can pay for dinner every now and then.
Last April I attended the Bethenny show- my boyfriend got major points for attending with!, and her guest speaker was Farnoosh Torabi, author of When She Makes More, phenomenal book. In it she talks about keeping your checking accounts separate, but also having one joint account where you can use it for household expenses, trips, etc.
Taking all this into consideration may save you some trips to the accountant down the road, and maybe even a few (thousand- think big!) dollars!
