Khloé Kardashianisn’t closed off to the possibility of getting married again.

In a sneak peek at Thursday’s series finale ofKeeping Up with the Kardashians, Khloé opens up about her future with boyfriend Tristan Thompson while filming an interview that will be placed in her family’s time capsule after the series ends.

“I hope I have a sibling for [my daughter]True, but also, I don’t feel incomplete if I don’t,” Khloé, 36, says when asked where she sees her life in 15 or 20 years. “I don’t know, I think I want to be married again. I think. But I also don’t think I need to be married in order to feel like this is our union.”

Khloé then hops on a FaceTime call with Tristan, who was in Boston playing for the Boston Celtics, to discuss their plans for the holiday season.

“So, I know that the holidays are coming up,” she says. “There’s so many things we have to discuss.”

Khloé then expresses her hesitancy to spend the holidays away from home, saying she “has to just think about it.”

“You should. I’m waiting on you!,” Tristan urges.

While the couple are in a good place in their relationship, Khloé explains that it’s “weighing” on her to make a decision regarding a permanent move to Boston.

“Tristan and I are in a way better place than we were before,” she says. “But I’m still trying to navigate my way through my feelings and I don’t know if I’ve really had time to think about what moving would mean for our relationship.”
