As you've no doubt heard by now, Tristan Thompson was caught cheating on Khloe Kardashian while she was pregnant with his child.
These days, Khloe is still living in Tristan's mansion (while he resides in a nearby hotel), and she's reportedly contemplating her next move.
Insiders claim Khloe will finally dump Tristan when she heads back to California for Mother's Day, but in the meantime, she's living in a situation that's been described as her worst nightmare.
Khloe has been dreaming about becoming a mom since she was a child herself, and sources say she'll never forgive Tristan for marring the joyous occasion with his betrayal.
Though she's reportedly putting on a brave face for her loved ones, those who know Khloe best say she's currently stuck in an emotional tailspin.
"Khloe is taking it one day at a time with Tristan. She is glad he is helping her out with True, but she has also been spending a lot of alone time reflecting," an insider tells E! News.
"They don't speak much about the situation, and Khloe feels like she is living in her own personal hell. The only thing keeping her happy right now is True and the support from her family," the source adds.
Khloe's family has reportedly issued her an ultimatum, basically telling her she needs to dump Tristan if she wants their continued support.
Insiders say Khloe's mother and sisters consider it a harsh but necessary move, as they're terrified that she'll give Tristan another chance only to wind up getting hurt a second time.
"Everyone is ready for her to come home and thinks it will give her more peace," the insider claims.
"Tristan has desperately been trying to keep Khloe happy and make their relationship work, but she thinks it's too far done."
Referring to Kim Kardashian's recent appearance on Ellen - during which she described Khloe's situation as "so f--ked up" - the insider says that while Kim is the only one in the family to express her feelings publicly thus far, everyone is in agreement that Khloe needs to cut Tristan loose.
"Kim was the only one to go public with her opinion, but they're on the same page and have similar feelings," the source claims.
The source adds that the Kardashians are not currently on speaking terms with Tristan, and they've implored Khloe to return to LA for good as soon as possible:
"They think Khloe is making the wrong decision and aren't happy. But leaving is easier said than done," the insider says.
"They are trying to be supportive no matter what, but they are a bit disappointed," the source adds.
"They don't think Tristan will change his ways and think that Khloe will be hurt again and again."
The original plan was for Khloe to remain in Cleveland until Tristan is done competing in the NBA playoffs, but Kim and company are concerned that by then it may be too late for Khloe to break free.
"The more time passes, the more comfortable she gets," the insider reveals.
"Her original plan to take True back to L.A. is off the table—for now."
