Khlo? Kardashian And Tristan Thompson Head To LA Hot Spots Craig’s For Dinner

She hasn’t moved back to Cleveland.

“Things are still quite up in the air between them,” a source told PEOPLE in October. “Things seem more unstable in the relationship right now. But she’s taking it all in stride.”

A second source said Kardashian wasstill making up her mind about how to move forward.

“Khloé isn’t saying that she and Tristan split. It seems she hasn’t decided yet what she wants to do about their relationship,” the source said. “And she seems fine about this. Her family is happy that she is still in L.A. and wants her around for as long as possible. No one is pushing for her to go back to Cleveland to be with Tristan. This will be her decision to make.”

By November, when Thompson’s cheating scandalbegan to unfold onKUWTK, a source told PEOPLE that Kardashian had been having a “really tough” time and“still has a lot of hurt and anger”toward him.

She’s gotten cryptic on social media.

Kardashian has been known to share inspirational quotes and messages with her fans on social media — and lately, many of themseem to be alluding to her relationship with Thompson.

Last month, she posted a poignant quote about being repeatedly hurt on her Instagram Story that read: “There will be some things you won’t get over. Some things that will sting you so hard they will set you back to where you started. And you will hurt and hurt and hurt. But you will also rise from it. You will learn from the past. You will adapt and survive no matter how hard it gets. You will shape your own reality and accept how you should never settle for anything less than you deserve.”

Last but not least, she hinted at tough times with a quote that read, “I wish I had the time for the nervous breakdown I deserve.”

And this week, sheposted a glamorous shot of herself, captioning it with a notable lyric fromBig Sean‘s “Memories.”

“Are you willing to give up what you love, for who you love?” she wrote.

She ‘acts like a single mom.’

Though sources haven’t confirmed whether Kardashian and Thompson are over, one insider told PEOPLE last week that Kardashian“rarely talks about” Thompson.

“Khloé and True are happy in Los Angeles. They spend very little time in Cleveland, where Tristan is,” the source said. “She very much acts like a single mom.”

The source added that Kardashian’s 10-month-old daughter is her main focus.

“Herwhole life is True,” the source said. “Khloé is a great mom. It’s so obvious how much she loves being a mom.”
