A dating mistake that Gen Z is most commonly making, according to a relationship therapist.

One relationship therapist claims that Gen Z's struggle to find love is largely due to the pickiness they've developed from using dating apps.

Jeff Guenther, a licensed counselor, has gained millions of followers on Instagram and TikTok under the name "Therapy Jeff" by sharing dating advice.

Gen Z, born between 1997 and 2012, has become too selective about their potential partners due to dating apps making it easy to filter out people based on superficial reasons such as height or appearance, according to Guenther's interview with CNBC Make It.

"Guenther stated that we can be too picky with our dating app filters, which limits our chances of finding a good match."

He provided an instance of individuals dismissing potential partners based on their height, despite height not being a reliable predictor of compatibility in relationships.

"He pointed out that many people are looking for men who are over 6 feet tall, even though only 11% of men meet this criteria. He added that this mindset often results in a lack of openness to potential matches who may not fit the initial criteria."

According to data from The League, women are more likely to reject potential matches based on their height or age, resulting in a higher rejection rate of 70% compared to men's 55%, as tracked by the American dating site in January 2023.

Young people are becoming increasingly anxious about finding love as they set high expectations for their future partners.

According to a recent EduBirdie survey of 2,000 respondents, a quarter of Gen Zers cited "not finding love" as one of their greatest concerns, while 22% said finding a life partner was one of their biggest challenges.

"According to Guenther, dating apps have caused us to prioritize unimportant things in relationships. He believes that this has created a culture where people feel like they don't have to put in much effort in relationships because they can always go back to the dating apps and swipe indefinitely."

He added, "I believe that's why many of us are commitment-phobic due to it."

Young people are fixated on identifying "icks" in potential romantic partners, as evidenced by a social media trend where they describe the instant they lost attraction to someone due to a perceived flaw.

TikTok has over 200 million posts about the "Ick," with users sharing their pet peeves about emojis, food orders, and clothing choices.

Gen Z is rejecting people on dating apps due to inconsequential details.

Guenther stated that there's an addictive quality to using dating apps, even when in a satisfying relationship, one can't help but feel the urge to get back on and try their luck again, as if there's always someone better out there.
