The reason behind their split seems to be primarily their financial problems, according to a source at People.

The insider revealed that Kim has been planning to divorce Kroy for a “long time,” and hasn’t told any family or friends.

“Money has been a big problem. The million dollar tax [payment] was just way too much pressure on them,” the source said.

It also added, “There is no cheating on either side. The money has a lot to do with the split, but there were other factors. He is managing [the family] for a long time, so technically he did have a job. They are not on good terms at the moment.”
