Interesting, here is a new article in the USA Today: https://www.usatoday.com/story/money/personalfinance/budget-and-spending/2018/10/28/cost-dating-relationship/38235365/
"Single people spend an average of $146 per month on dating, according to the poll of just over 1,000 people. People in a relationship spend a little less at $139 a month, while married couples spend only $130. It's not all bad news for married couples, however, as they spend more per date ($54), than people in a relationship ($44), or single people ($43)."
Just goes to show how inaccurate polling can be! Let the buyer beware!!
