On last night's episode of Kourtney & Kim Take Miami, viewers were taken back in time, as the installment dealt with Rob Kardashian's two-month-old Tweet where he accused Rita Ora of cheating on him with "nearly 20 dudes."
What inspired Rob to take such a dig at his ex?
"I posted what I posted to keep myself from taking her back," Rob said in his own defense. "Every time she messed up, I took her back for over a year now. I just had to do that to make her hate me."
Throughout the episode, Rob's sisters tried to reign him in.
Kim Kardashian, for example, told her brother:
"There's just no point [in tweeting]. You loved her for a reason. You aren't together for a reason now. You just always have to take the high road."
Kourtney Kardashian, meanwhile, was concerned over how Rob would come across compared to his ex: "She's the one who's in the wrong but she'll probably try to make it like you're in the wrong for posting it."
Overall, Rob doesn't sound like he has any regrets, except for this:
"I don't want people to think I'm being a bitch."
