I have an issue with your post. You say there is all this evidence but then you say allegedly these are texts. You can't have both.
Women don't get called liars just like that and I fully understand how serious abuse is. But problem with any kind of abuse of women or men is that the more you wait, the less of credibility you have. If photos from above are six months old, why didn't she report him then? As cruel as it sounds, you have to do it immediately, if you don't you only have yourself to blame.
Not to mention the fact that she didn't walk out on him after all this alleged abuse. And she's fully financially independent. Not as rich as him but she's also not in position of many women who have to stay with abuser because they have no source of income.
In many instances of crime, if you wait long to report the crime the case falls apart. Abuse is no different. Not to mention that guy has a bad reputation, so what does it say about Amber that she was attracted to him? Was it only charm, was it fame and money? We'll never know.
I remember when I first heard that Charlize Theron was dating Sean Penn, man with enormous history of abusing women. Maybe some women are attracted to those "bad boys", no idea. But it's sad.
I still don't know what to think about this case. Seems like two crazy people met each other and here we are.
