Things are no longer amicable between Kristin Cavallari and Jay Cutler, a source tells ET. According to the source, things have turned sour for the pair — who announced their decision to divorce on Sunday after 10 years together — after Cavallari requested primary custody in divorce documents. «Kristin and Jay planned to keep everything amicable, but that's not the case anymore,» ET's source says. «Kristin filing for primary physical custody upset Jay.
He loves his children more than anything and thinks the couple should be reasonable and split custody.»«Kristin has made comments about possibly moving back to L.A., which is also a concern of Jay's, as home for the family is currently Nashville,» the source adds.
