Gwen Stefani is reportedly "putting on a brave face" about her marriage in front of her children.
The songstress and Gavin Rossdale got together in 1995 and married in 2002. They have sons Kingston and Zuma together.
Their relationship was rocked when a paternity test revealed Gavin had previously fathered Daisy Lowe with ex-girlfriend Pearl. Courtney Love also claimed that she'd had an affair with him.
Gwen is said to be doubting her long-time partner.
"Things have gone from bad to worse and they don't know how to fix it. They've been through a lot and while Gwen's putting on a brave face for the sake of the kids, she's not sure she can save their marriage," a source told British magazine Closer.
Gwen has reportedly suggested a temporary break from each other.
"Gwen isn't sure she can trust Gavin any more. They need time to figure things out, but he's now on a six-month world tour with Bush until the end of June - although he tries to come back when he can to see the kids," the insider added.
"Rather than trying to have a long-distance relationship, Gwen suggested a trial separation to see if a break would prompt him to show her how much she means to him."
