How Did Charlie Sheen Betray Brooke Mueller?

This headline seems like a silly question, doesn't it?
After all, Charlie Sheen allegedly held a knife to Brooke Mueller's throat on Christmas Day; shacked up with a model soon afterward; and, most recently, went on a cocaine-fueled rampage in a NYC restaurant and hotel with porn star Capri Anderson.
But Mueller's lawyer, Sorrell Trope, actually cites a different reason for how Sheen "humiliated" Brooke on Monday.

As previously reported, the couple signed off on a divorce document this week that they first agreed to back in May.

Trope tells TMZ the two sides were meant to wait a year before officially splitting, as such an agreement was made because his client "didn't want to make trouble for Charlie" while he was facing assault charges.

Mueller was reportedly "blindsided" by Sheen's decision to file now and considers it a slap in the face because she remained supportive of him during last week's shenanigans.

Responds Mark Burg, Sheen's manager: "Charlie tried to reach out to Brooke and left her a message before filing for divorce.  It's a shame that this ambulance chaser is trying to drum up more business because this divorce was finalized and agreed upon 6 months ago.

"Shouldn't everyone involved be more concerned about the two young children?"

Good point, Mark. We assume you're referring to Sheen as one of these children, right? Who is the second one?
