Real Housewives of Orange County's Gina Kirschenheiter's husband Matt was arrested this past weekend after a domestic violence call Saturday. But the trouble didn't stop there, of course ...

Matthew was released the following morning around 1am, without bail. He wasn't officially charged with a crime but law enforcement says the arrest was related to a domestic violence call.

The incidence happened only days before Gina was in court for a protective order -- she had requested an emergency hearing due to allegations of violence by Matt. The couple are in the middle of a divorce but seemed to have reconciled. We're guessing that reconciliation is OFF now.

Just ten days ago, Gina was wishing her now-estranged hubby a happy birthday with this touching post: "Happy birthday to the man who has held my hand for the last 14 years despite the ups and downs. Thanks for being the best father to our kids, and the best friend a girl could ask for. Wouldn’t want to take on this crazy life with anyone else. Like you said, ‘I’m your person and you’re mine.'"

Wow! Things change ... and quickly!
