We can see why!

Khloe Kardashian's family had reservations about her romance with Tristan Thompson when they first began dating, and now those have been validated after he was caught cheating on her just days before she's set to give birth!

"When Khloé first started dating Tristan, her family questioned if it was a good idea. There were several concerns, including that he is another basketball player and also that his ex was pregnant. It took a while for the family to accept Tristan. They were worried that Khloé would end up heartbroken," a source told People.

"Being on the road as an athlete, you face many temptations. But Tristan always assured Khloé’s family that he was totally committed to Khloé. Khloé thinks the world of Tristan. They are heartbroken for Khloé," the source added.

Apparently, his infidelity wasn't a one-time thing, either!

"Tristan has been consistently cheating on Khloé. He’s a serial cheater. And there will be more women to come out of the woodwork. First Lamar cheated on her and now Tristan. She’s been through so much," another source revealed.

The reality star didn't think her man was capable of this type of betrayal, so all of this comes as a complete shock.

"As far as she knew, there were no negatives. Once she made the decision to commit, she was all in and trusting. He was her everything. They had a life together. She honestly thought he treated her like gold, like a queen. [He] gave her everything, doted on her, told her how beautiful she was. To her, life was perfect. And it all just came crashing down," the source explained.

Khloe needs to find a nice guy that treats her right and stay the hell away from athletes!
