Although the 31-year-old reality TV star called off proceedings while her 36-year-old ex Lamar Odom recovered from his near-fatal collapse in a Nevada brothel last year, she is upset that he has started partying again and is reportedly set to move ahead with dissolving their marriage.

A source told PEOPLE that Khloé is "ready to move on".

The insider added: "She doesn't agree with some of Lamar's choices in the past few weeks. She plans on refiling for divorce soon. She and Lamar are just figuring out the finances first.

"Khloé was there for Lamar when he needed her. She spent months making sure he got the best care and was able to recover. Lamar was her main focus, and it was draining for her. Lamar is ready to be on his own now.

"They will always be friends, but Khloé is ready to move on."

News of the divorce comes after Khloé recently suggested she is "letting go" of Lamar.

She posted a quote on Instagram which read: "It doesn't matter how loyal you are to someone. You can't change someone's heart and bad habits unless they want to themselves."

And Khloé added in a heartfelt caption: "Letting go doesn't mean that you don't care about someone anymore. It's just realizing that the only person you really have control over is yourself.

"Letting go with love takes great strength. We have to learn to stop taking on peoples problems as if they are our own. Loving people does not mean we have to carry their burdens and confusions on our back.

"Sadly, You can only express your opinion on a situation. You can't want their life more than they do. This is in fact their life to figure out on their own and in their own time.

"I do believe in timing. I do believe timing is everything. You forcing your beliefs and dreams down ones throat is only going to cause resentment and possibly manifest deeper issues. Possibly to the point of no return.(sic)"
