IF YOU'RE TOO YOUNG WHEN YOU START DATING
During an episode of Life of Kylie, the youngest Jenner sister revealed that the end of her on-again, off-again relationship with rapper Tyga wasn't the product of a major blowout. In fact, the split, according to the Kylie Lip Kit creator, had to do with their age difference.
“There was no crazy fight, we just decided…Well, I decided that I’m really young," said Jenner. "I don’t want to look back in five years from now and feel like he took something from me when he’s really not that type of person.”

IF HE TRIES TO DIVORCE YOU VIA TEXT
"He's a very smart man, and I was in love with him when I married him," Katy Perry told Vogue in an interview for its July 2016 issue, opening up her marriage to Russell Brand. "Let's just say I haven’t heard from him since he texted me saying he was divorcing me December 31, 2011." The pop star went on to imply that the comedian couldn't accept her as an equal, another dealbreaker.

When Harris finally opened up about his June 2016 split from Taylor Swift, he cited a few reasons why the breakup felt inevitable.

IF HE'S 'SO GOOD' AT CHEATING
After filing for divorce from Lamar Odom, the reality star candidly discussed his infidelity on Howard Stern’s SiriusXM show. "He was so good. Nothing was on his cell phones, he had an assistant and they were all on his assistant’s phones so he was really crafty,” she told the host. "It’s disgusting, and I was pissed at the assistant. And all these rumors kept coming out in the weeklies, and as much as I know they’re bulls—, where there’s smoke there’s fire. Something has to be right here. But then this one girl did an interview and she was so adamant and when I confronted him, he blamed another teammate. This was when he was playing for the Clippers, his last season. Once I found out about all the cheating, I was very worried about STDs. I went and got checked. I’m clean, thank God."

IF HE'S EXPECTING A BABY WITH HIS EX-GIRLFRIEND AND DOESN'T TELL YOU
The rapper let it all out when she took to Twitter to explain the reason she broke it off with former fiancé Nick Young. “I have never even been told by Nick that his baby mother is pregnant, so if this is true, I’m finding out via E! News,” she wrote, referencing reports that Young was expecting another child with his ex-girlfriend. “I broke up with Nick because I found out he had brought other women into our home while I was away and caught them on the security footage. This is just like a second shot to the chest.
