When you’re in a committed relationship, some things can be combined and others should remain separate…like your Facebook accounts.

According to a new study out of Indiana University, one secret to a longer, happier relationship may be consolidating your finances.

The study followed 230 engaged or newly-married couples across two years.

Some couples were asked to keep separate bank accounts, others were told to open a joint bank account and a third group could choose for themselves.

The couples who opened joint bank accounts reported significantly higher relationship quality than those who kept separate accounts.

The researchers believe this shows that merging finances leads to “aligned financial goals, increased transparency, and a shared understanding of marital responsibilities.”

We like a joint account for the bulk of the money with separate accounts for each to have some “fun money” they can use however they want…what say you?
