Their financial situation
According to a poll of more than 1,300 single adults, approximately one in five men said that they lied to their dates about their financial situation. Men with a lower income lied about earning more, to impress their potential dates; at the other end of the spectrum, men with higher incomes did not want their dates to know how much they made to make sure money was not the decisive factor in their future relationship.
As a matter of fact, according to another survey conducted in 2023, 86 percent of male online daters and 74 of female daters hid the truth about at least one aspect of their profiles, income being among those lies.
According to the National Endowment for Financial Education (NEFE), a simple lie about income at the beginning of the relationship can turn into downright financial infidelity throughout the marriage/relationship. In the long term, it will only cause arguments and maybe even lead to divorce/separation.
