Struggling to land a lady? It may come down to one of these five fatal faux pas.

Dating guru Louanne Ward is revealing the common relationship blunders that men commit, which can turn off women and kill their attraction instantly.

“Once she sees it, she can’t unsee it,” the expert asserted in the caption of an Instagram post she shared last month. “And the spark? Gone.”

First, Ward warns against men engaging in “cutie baby talk” during the courting process.

According to Ward, talking down to a woman in a condescending manner, as if she were a pet, child, or sidekick character, is a major mistake that men make. This behavior is not endearing; it is cringeworthy and can make a woman mentally check out of the conversation.

Additionally, Ward highlighted the importance of displaying proper table manners during a dining experience with a potential romantic partner. Failing to do so can be a serious turn-off and ruin the mood of the date.

Thus, her second no-no: Picking at your teeth during a meal.

“She’s trying to focus on the conversation, and you’re elbow-deep in your own molars,” the expert hypothesized of the horrifying behavior.

“Bad breath is one thing. But picking food out of your teeth with your nail? It’s not just a hygiene fail, it’s a primal repulsion.”

The remainder of Ward’s mistakes pertain to technology, including the way that men present themselves on dating apps.

Posting pouty selfies and AI-generated profile pics is classified as her third fatal mistake.

“If your dating profile looks like it belongs in a Marvel casting folder… she’s not swooning. She’s dry,” the no-nonsense blonde blasted.

She additionally advised against fellas faking a smolder while posing for any pictures posted online.

“You think it’s seductive, [but] she thinks you’re auditioning for an off-brand aftershave commercial. She’s gone,” Ward said of the try-hard “perfume-ad stare.”

Ward’s fifth and final faux pas: men who can’t control their temper when engaging with technology.

“Shouting at the remote. Throwing your phone… It’s not passion. It’s pressure. And pressure doesn’t feel safe,” she explained.
