Khloe Kardashian and Tristan Thompson's relationship is still ''up in the air''.

The 'Keeping Up With The Kardashians' star's world was rocked when her partner was seen seemingly kissing another woman just days before Khloe gave birth to their daughter True and they are reportedly still struggling with their relationship.

A source told People magazine: ''Khloé is stable, content and very happy with being a mom and with how things are going with True. As for Tristan, things are still quite up in the air between them. Things seem more unstable in the relationship right now. But she's taking it all in stride.''

It comes after a source claimed Khloe is ''holding off'' on moving to Cleveland.

They explained: ''She isn't ready to leave her family just yet. True will be six months old soon and Khloe plans to spend that special day with her family ...

''As much as she's worked on moving past the heartbreak, the reminder brings up some of those emotions again. Khloe will most likely head back to Cleveland, but as of now, there isn't an official date.''

The incident has eroded the reality star's trust in Tristan.

A source said: ''Khloe has seemed emotional. Her feelings about Tristan cheating is something that she is still dealing with. She has good weeks when she is fine about it and weeks when she is upset about it. It's of course difficult to trust someone 100 percent who cheated days before he was about to become a dad. Khloe still struggles with this sometimes. She wants to move back to Cleveland, but she isn't sure what date she is [going]. The move is postponed for now.''
