Separated! 'Vanderpump Rules' Scheana Marie & Mike Shay's Marriage Breaks Down

Scheana Marie's marriage is on its last legs.

The Vanderpump Rules star's husband Mike Shay stormed out of their home last week following a blowout fight and refuses to return, RadarOnline.com can exclusively reveal.

"Mike found out some things about Scheana on Wednesday, and was furious," a family member reveals to RadarOnline.com, adding that the musician — called "Shay" on the Bravo show — is now staying with relatives.

As RadarOnline.com previously reported, rumors that Shay, 29, disappeared with the couple's savings in a drug-fueled haze are not true. Rather, the still-sober rapper left his 31-year-old wife following the ugly argument, the insider insisted.

The fight wasn't centered around infidelity, but rather the actress' inability to support her husband's career, the source explains: "Now that things have started to click for him, there's been some jealousy."

"Right now, the marriage is beyond repair," the insider says, adding that neither side has drawn up divorce papers just yet. "They both need to make a decision on the future of their marriage, but no one has made a move at this point."

Shay and Marie, who tied the knot in 2014, have struggled with problems since the early days of their marriage.

Last year, the reality star struggled with her husband's admitted prescription pill problem. However, all seemed well when Shay promptly sobered up.
