Money management can make or break a relationship.
Lifehacker has tips on how to approach finances with live-in spouses:
Draft documents like a cohabitation agreement or prenup.
"(It) won’t solve all potential future problems, but it will make them easier to manage should you and your fiancé ever break up."
A joint bank account also allows each person to make deposits for bill payments.
Make a budget detailing all home costs. This includes who buys the sofa or TV.
