The couple welcomed their baby girl on Thursday.
A source close to Kardashian tells ET that the reality star is not planning to break up with her NBA player beau amid reports that he cheated on her with multiple women. In fact, the source says "it's not even on the table right now."
"They are both 100 percent committed to moving past this and focusing on the overwhelming joy they have in their life right now with their new daughter," the source shares. "Tristan knows he's got to step up now though and can't screw up."
"They're only looking forward, not backward," the source adds.
Kardshian gave birth to her and Thompson's first child together at a Cleveland-area hospital early Thursday morning, just days after cheating headlines surfaced. ET learned that Kim and Kourtney Kardashian, Kris Jenner and Malika Haqq were with the Revenge Body star in the delivery room, while Thompson was spotted leaving the hospital that day.
Kim and Kourtney flew back to Los Angeles on Thursday. "They have families and young kids to get back to. They were never planning on staying long even before the scandal," the source explains. "Plus, Khloe will be back in LA very soon.”
While a source told ET that Kardashian has decided to return to LA as soon as her daughter is able to fly -- "Right now, she realizes she needs her family around her and knows they are the people in her life that she will always love and trust," the source said -- another source revealed that she isn't ready to give up the love and security she feels with Thompson.
"She loves him, and it looks like for the time being she isn't ending their relationship," the source continued. "She is in no shape to make that decision right now."
