If these 10 things happen in your relationship, you’re meant to be together!

8. Your Spending Habits Differ

You’re certainly not alone if you find that the majority of the arguments you have as a couple are sparked by personal (or combined) finances. In fact, a Money Magazine poll found that a whopping 70 percent of couples argue about finances the most—more than household chores, togetherness, sex, snoring, and so on.

But if the two of you have stark differences in the way in which you prefer to spend—a.k.a. one of you is a spendthrift and the other is a tightwad (yes, that’s an actual term)—you just might be perfect for each other. The proof is in one study by the Universities of Pennsylvania, Michigan and Northwestern. Researchers surveyed over 1,000 married and unmarried couples, and found that most individuals tend to choose their spending opposite when it comes to selecting a lifelong partner.

So if that sounds like you and yours, you just may have the perfect yin-and-yang combo to make things work. “Just remember to prioritize the big-spending opportunities like buying a car, house, etc,” reminds Dr. Greer.
