According to reports, the couple have been fighting a lot lately and Bruce feels Kris treats him like a door mat, reported Showbizspy.
"Bruce feels that Kris treats him like a doormat, and he's had enough. She constantly belittles his appearance and complains to mutual friends that he's a boring. Then she has the gall to flaunt her relationships with younger guys in his face.
"One of Bruce's pals who's a sports entertainment lawyer has helped Bruce value the assets of the Kardashian-Jenner empire if he moves forward with a split. He's also talked to a divorce attorney buddy about potential custody arrangements for his two girls with Kris," a source said.
The couple have two kids together - Kendal and Kylie Jenner. Kris also has four kids from her previous marriage.
