Johnny Depp and Amber Heard's relationship was "non-stop drama".
Amber was granted a temporary restraining order by a judge last week after alleging that Johnny physically assaulted her and according to close pals of the former couple, their relationship was always volatile.
A source told PEOPLE: "With Amber, there has been nonstop drama. [Johnny and Amber] are just not good together. They had lots of problems before they got married, and should have never gotten married. Their personalities are just not compatible.
"He is very insecure when it comes to Amber. After the recent drama, people close to Johnny feel a divorce is the best outcome. Johnny and Amber should not be married."
Amber, 30, filed for divorce last week, three days after Johnny's mother Betty Sue Palmer passed away.
And she claimed in court that her decision to file for divorce was prompted by Johnny, 52, physically attacking her with an iPhone, leaving her with a bruised eye.
Amber said in a written declaration to the court that she had "endured excessive emotional, verbal and physical abuse" during their 15-month marriage.
She wrote: "During the entirety of our relationship, Johnny has been verbally and physically abusive to me. I endured excessive emotional, verbal and physical abuse from Johnny, which has included angry, hostile, humiliating and threatening assaults to me whenever I questioned his authority or disagreed with him.
"I live in fear that Johnny will return to (our house) unannounced to terrorise me, physically and emotionally."
Despite granting the temporary order, which instructs Johnny to remain 100 yards away from his wife at all times, Los Angeles Superior Court Judge Carl H. Moor rejected her request for Johnny to attend one year of anger management classes.
He also did not accept her request for the restraining order to extend to keeping the actor away from her Yorkshire terrier.
The pair are not thought to have put a pre-nuptial agreement in place before they wed in February 2015 in Los Angeles, followed by another ceremony in the Bahamas.
The former couple met on the set of 2011 film 'The Rum Diary'.
Johnny previously divorced his first wife, make-up artist Lori Anne Allison, in 1985 after just two years of marriage and he split from French actress partner Vanessa Paradis - who he has daughter Lily-Rose, 17, and 13-year-old son Jack with - in 2012 after 14 years together.
Amber was in a three-year relationship with girlfriend Tasya van Ree until 2011.
