A source tells PEOPLE that Khloé, 33, is trying to work out the best way to celebrate True’s April 12 birthday after Thompson, 27, was accused of hooking up with Jordyn Woods, a longtime friend of the famous family.
According to the source, Khloé’s family members — in particular sister Kim Kardashian West — are furious with the basketball player, who was first caught allegedly cheating on Khloé last year when photos and videos surfaced of him getting close to other women just days before she gave birth to their daughter.
“Kim never trusted Tristan after he cheated on Khloé right before True was born,” the source says. “Ever since, it’s been very difficult for Kim to even tolerate Tristan. But she really tried her best because it was important for Khloé.”
Now, Kim “says she never even wants to see Tristan,” the source says. “She feels there is no chance she will keep it together and not lose it on him. Kim is beyond angry with him.”
So for True’s birthday, “Khloé is figuring out how to get Tristan involved,” the source continues. “She can’t see how he can be around her family at a party, though. Everyone is just too upset with him.”
Sources have previously told PEOPLE that regardless of the status of her relationship with Thompson, Khloé wants their daughter to feel supported by both her parents.
“She’s very good at compartmentalizing and at the end of the day, she wants True to have a happy relationship with both of her parents,” one source said. “She’s not one to seek revenge or hold onto negativity.”
Another source told PEOPLE last fall that Khloé “wants True to spend as much time with her dad as possible.”
“She believes that True needs a mom and dad in her life,” the source said.

As for Khloé herself? She’s leaning on her family as she attempts to move past the most recent scandal.
“Guys may come and go, but the bond between the [sisters] is never going away,” a source recently told PEOPLE. “And they’re committed to supporting each other.”
