I honestly don't know much about them or their marriage right now. But "still together," without context, doesn't mean shit. For example, many people remain in abusive or unfulfilling relationships for years, or even their entire lives. Sometimes the best thing to do is call it quits and move on.
I'm worried about the kids because I see a lot of danger signs. Other than the publicity they may receive from their notoriety they don't have a lot of prospects. Vili sounds like he's already moving towards alcoholism. Then there's the fact that this lady is already known to prey on children. No one is going to want to send their kids over to play at their house, if they're not already ostracized from the community.
Call me a cynic but I don't see this having a fairy tale ending.
