I think Johnny Depp just gave many men an idea of how to keep their careers going when the women in their lives destroy their careers

 Though many women might be horrified by what just happened to Amber Heard you also have to realize that she had an affair with Elon Musk one month after she married Johnny Depp so you get the just of all this. This was obviously a very strange relationship to begin with if she went out on Depp within the first month they got married?

Although we don't know what Johnny Depp was doing at that time either it didn't look good that she did this to him the first month of their marriage.

So, why did she marry him? For the money it seems like and for the notoriety it appears. So, from the beginning she seems very mercenary in her approach to Depp and not loyal to him in any way which means a relationship like that could never be a real marriage.

I think Johnny Depp really had no financial choice other than to sue her for damages to his career. It was a financial necessity for his financial survival no matter what she did in the past or future to harm their relationship.

However, it is unknown what will happen to either johnny Depp or to Amber Heard in life after this. These kinds of things tend to really mess people up in their lives no matter how financially successful either of them are after this.
