I don’t know about this study, but I can tell you that seven years ago my family was living pay check to pay check at best and my wife and I would worry about money and bills and had arguments daily. Today we don’t even look at the bank account. We pay bills, buy what we want and never worry a minute about money because we have a very nice cushion. What a difference having money means to a relationship. (We are not rich but we have enough to not sweat money issues every night). The only discussions we will probably have is buying a car, house and major things like that. It is 100 percent wonderful.
That is wonderful I am glad to hear you have enough money so that you don’t have to worry about it, same here. But one of the most miserable people I know also has the most money of anyone I know. Tons of money has not made her happy.
