I think if you have seen abuse first-hand you recognise it as a pattern of control and although Johnny behaved badly at times, it's obvious he did not have the hallmarks of an abuser. For example he paid to have Amber's family live with them - abusers isolate. As another example he tried to leave during fights - abusers will not do this.
I experienced a very similar situation with a male in real life who, like Johnny had a troubled childhood. He met a woman who was an abuser and, like Amber, she deemed him someone she felt she could make use of so she set about manipulating him into a relationship.
She ingratiated himself in a similar way when he was in a low point and, similarly, spending time with her at work in a close environment. First pretending to be his best friend, keen to talk about her marriage breakup and troubled childhood, Feigning the same interests and a deep connection as friends - Johnny's statement described the same with Amber.
Once ingratiated as a "best friend", she pushed for emotional dependency and isolated him from other friends and family by being insistent on spending every minute with him, which felt flattering. She laid the kindness and the adoration on very thick then encouraged him to consume vast amounts of alcohol which led to sex after some months.
After that, she pressured him to let her move in with him. Showing up at his door drunk and crying, playing the damsel in distress and asking to sleep on his sofa because she 'needed him'. Over a short time he found himself more or less living with her, and once in this position of trust the real her came out.
She would have rages at him when he would not do what she wanted, she isolated him completely from others, she began to threaten to hurt herself if he didn't love her back, she began to threaten to expose personal secrets he had disclosed and she spread false information about him to his loved ones so they cut him off.
After a few months of this "relationship" he was on medication for stress, drinking heavily and had come to believe he was responsible for her abuse (which he did not recognise as abuse). He was made to believe the problem was she loved him so much, and he didn't return those feelings so it was his refusal to commit to her which caused her behaviour.
If he tried to leave she would say she could not live without him, or make threats, or beg for him to look after her and he almost lost his job due to things getting so crazy. She hit him, she smashed his property, she deprived him of sleep, she faked pregnancies, she lied to everyone about him, she controlled his communication, she gaslighted and made him ill.
Of course there were times he got angry, times he locked himself in the bathroom to escape (just like Johnny) and times he wrestled her to get her away from him but it did not make him an abuser- this was self defence.
When he finally got help to leave, she initially stalked and harassed him to the point the police had to get involved, and then she tried everything possible to ruin his life - from false allegations to flying monkeys.
This man's life was ruined, and whatever his faults he did not deserve it. Two years later he has PTSD and flinches if people raise their voice. He suffers from auto immune disease and is tired and sick and the time. It's been really awful.
I wish he had known two years ago that men like Johnny Depp experienced this too because he believed there was something wrong with him, he didn't understand it was abuse and what Johnny is doing might save many men from the same.
