A WOMAN who caught her man cheating when she was pregnant with his baby has shared her "foolproof hack" to find out if your partner will be unfaithful.

Kira Arellano, 19, has gone viral on TikTok after claiming her method of predicting whether or not a future spouse will cheat works "100%" of the time.

The behavioural health technician got engaged to her now ex-fiancé just four months into a whirlwind romance.

She decided to accept his proposal despite the fact she'd found out about his infidelity just three days beforehand.

So, to protect herself both financially and emotionally, she insisted on having a prenuptial agreement in place.

In the legal document was a clause stating that if someone in the relationship cheats, the other half is entitled to compensation.

"I brought up the prenup and infidelity clause, which he was very uncomfortable about," she told NeedToKnow.Online.

"Eventually, he did reluctantly agree, although he showed lessened intentions of getting married after that."

Kira added that up until she suggested the prenup, he had been "adamant on getting married and having a baby".

"For context, he proposed three days after I found out he was cheating and at the time, I decided to forgive him as I convinced myself that I loved him for survival purposes.

"As far as wedding planning goes, we had some very brief conversations about venues and I picked out a dress, which I absolutely fell in love with – but after the prenup conversation, the planning didn't really continue."

Soon, the pair called it quits after they started frequently arguing, where Kira recalls realising she couldn't "change him".

And she now lives by the motto: "Once a cheater, always a cheater."

She also decided not to have the baby.

Kira's video on TikTok has racked up 2.7 million views and 498,000 likes since she posted it, with the majority of people agreeing with her prenup suggestion.

"No matter how much you love the person GET A PRENUP," one commented on the video.

"Don't ever get marry without a prenup. Also put something in case you or him get sick," another added.

While a third wrote: "Prenups should be standard…it's not a bad thing.

"Protect yourself always. If he loves you, he will sign it."

"I'm very thankful that I got out of that relationship and prevented myself from being stuck in a marriage with someone who doesn't love me and never loved me," Kira said.

"I never cheated on him, I tried to be the best girlfriend and I know that whenever I do decide I'm ready to start another relationship, I will be confident that I can carry myself out to be a good partner."
