A new study reveals that infidelity, along with other social aspects of life, has shifted online during the pandemic.

Last year, a survey found that 17% of chat room users were cheating on their partners. Now, said the authors of the study, more couples than ever are engaging in extramarital affairs through online dating apps, adding that 25% of all marriages experience cheating.

According to Fox News, psychologists from the University of Tennessee-Knoxville wrote an editorial on the topic called Infidelity in the Time of COVID-19 that was published in the journal Family Process. The authors said that the “increased stress from the pandemic may be contributing to more negative perceptions for individuals of both their partner and their relationship.”

AshleyMadison.com, a website catering to discreet online dating services for married couples and those in a relationship, reported 17,000 new accounts daily since COVID-19 emerged, compared to 15,000 daily last year in the same time frame. According to Fox News, even personalized pornography is on the rise.

Psychologists Kristina Coop Gordon and Erica A. Mitchell, the authors of the new study, said that “research has consistently found increases in stress to be associated with decreases in both sexual and relationship satisfaction.” They added that the financial setbacks caused by COVID-19 along with social isolation also played a role in the increase of online infidelity.

Divorce lawyers have predicted that the coronavirus will spike the number of divorce cases in America. While not all experts agree that being quarantined is the main reason couples are splitting, they believe that if there were rifts in the marriage before lockdown, the 24/7 forced togetherness widened the split.

According to Parent Herald, relationship coach Lee Wilson said couples might have had disagreements in the past, but the quarantine made it worse. Wilson said the constant tension could trigger the divorce button.
