See this is the problem with such vague information. It could be any story that comes out. He said 'saw CW at the punch tavern' which is the punching you allude to? It is actually a chain of pubs

The thing you have to ask yourself is if it is true why would someone want to be labelled an abuser? Even if the case is dropped and they get back together he will still have that over his name.
And on the flip side she will be seen as someone who isn't prepared to stand up to her attacker which doesn't go down well with her campaign of anti-bullying.
But the main thing is that the fathers/family would know the person is dangerous. The kids are one of the ways she makes money so if she stopped seeing them = less money. Not to mention the actual fallout from the police if it was found out to be true.
Personally I think what happened is that CW did split up with her. His goal is/was to become a celebrity. After a year together he wasn't getting the exposure he wanted, not making any money. And if anything his image was being destroyed.
He said he was ending it a few days previously. KP then feels she isn't in control and sets up a way to get to him. To make him look bad and have something to bargain with. They get drunk/drugged up as they are addicts. She provokes him. He wants the ring back, she won't give it trying to provoke more and they have a physical altercation.
What is important to understand is that the police/ambulance can only say the time they arrived. It doesn't include when the actual event happened. This means the physical part could have happened a lot earlier in the day. The neighbours even said they heard the argument around 10.30pm-11pm.
The report doesn't say a time when he was nicked but it would be after the call out at 1.30am. They also don't say if he was arrested at the property or somewhere else.
Just enough time for her to call people, set up the interview/photos and get that make up on.
Now why would she do that? Control, nothing more. She agrees to drop charges and not help the police in exchange for him being silent.
That is my theory.
