Khloe Kardashian is ''not ready'' to divorce Lamar Odom.

The 'Keeping Up with the Kardashians' star filed for divorce from the basketball player in December 2013 but he never responded to her petition, and she has failed to go to court and get a default judgement, so the case is expected to be dismissed in the coming days as they are not ready to ''close the door'' on their marriage.

The former couple have been in contact, but they are not talking about a reconciliation, though sources told TMZ they still have feelings for one another.

However, Lamar, 35, is said to feel ''betrayed'' by Khloe and she has told him she wants a ''grand gesture'' before they can take the next step but he is not willing to do anything.

And sources close to the 'Keeping Up with the Kardashians' star says she has a ''big heart'' and worries about hurting the sportsman by ending their marriage, but she also still has feelings for him.

Khloe - who has dated French Montana since splitting from Lamar - recently admitted she ''doesn't believe in'' divorce.

The 30-year-old star - who split from Lamar amid rumours he had used drugs and been unfaithful to her - said: ''I don't necessarily believe in divorce, but I do think there are certain reasons why you have to end a marriage. I'm still going through my divorce and I wish I didn't have to do that.

''I love Lamar a million per cent. I turned 30 last June and by the time I hit that age, I thought I'd have kids and still be married. But because that's not the way it went, you can't sit in a ball and cry.''
