How long can the Mccann stay together?

Most families around the world,that suffered the pain of a child loss,can stay together.
The loss made them stronger.
But in this case the guilt rusts the relation.
Gerry didn't care about the kids,Kate had to do all by herself(as she said in her diary).
Both left the kids alone to go in Tapas Bar(anyway,WHY DIDN'T THEY CALL A NANNY?).
The media pressure is huge,the suspects of killing Maddie is also horrible.
Guess they won't support this too much longer.
