Amber Heard Text Messages with Depp's Assistant proves abuse

Amber Heard has released a screenshot of her text messages with Johnny Depp’s assistant, exchanged before her marriage to Depp, which appear to prove that he had been violent towards her, even before they got married. The assistant said that Depp “cried” when he was told what he had done to Amber. Which begs the question whether, if true, whether Depp is on some sort of substance that makes him go into rages and then promptly forgets it. Or whether he has some sort of psychological disorder. Because why did his assistant have to tell him what he had done? Does he not know what he has done? It seems rather strange, that conversation. It only makes sense if Mr Depp has a drug or alcohol problem. And a severe one at that that takes his memory after he rampages.
