Help! How Do I Handle Making More Than My Partner?
Even for couples who get along very well, money can be a point of contention.
Sometimes one person spends more than the other; in other cases, there are disagreements as to how money should be spent. Perhaps one member of the couple believes in saving and caution, while the other leans toward instant gratification.
All of those issues can be solved via communication and negotiation. It can be harder, however, for couples to deal with issues of income disparity. If one person starts making a lot more than the other, it can cause resentment and lead to problems that are harder to talk about.
