Well, they're trusting her judgement.
"They are supportive of whatever works for Khloe and True and they’re all for her spending time with Tristan, so long as he’s good and loyal to her. They all do really love Tristan," a source close to the former couple told Hollywood Life.
According to the source, the Kardashians know that KoKo "do what is best for her and her family" and understand that she is not seeking to get into another relationship with Tristan.
"They’ll be there for her with whatever she needs. Khloe seems to be really happy right now with the progress she’s made with Tristan, both as co-parents and within themselves. And if Khloe’s happy, that’s really all that matters.
"Khloe is very clear they’re not back together at this time and everyone, including Tristan, is aware of this. There are feelings of love there, but they are not romantically involved at all at this point."
A friend of Khloe's also told Us Weekly that her main focus is making sure True has the most normal and peaceful life possible.
"Khloé doesn’t have bad or negative feelings toward Tristan at this point," the source dished. "Being quarantined has made her have a soft spot for him, and she knows he will always be part of her life in some way because he is True’s dad. Khloé has been open and receptive toward Tristan."
On the most recent episode of Keeping Up With the Kardashians, we saw the beginning of Tristan making amends for his actions, firstly by making peace with Kim.
After running into Kim in New York, they had dinner together and was later invited to have lunch with the family in Calabasas, much to Khloe's displeasure.
However, it looks like it all worked, because living together is a big step!
But who wouldn't want to be around True's cute little face all the time?!
