Was this Bollywood actor's ex-wife the reason for Arjun Rampal-Mehr split?

The couple was trying to make their marriage work but couldn't, friends say.

Actor Arjun Rampal and his wife Mehr Jesia announced their mutual decision to separate after 20 years of marriage yesterday.
The couple have two daughters - Mahikaa (16) and Myra (13) from their marriage. Before going separate ways, the couple gave their marriage a second chance three years back. They started making public appearances together but that didn't last for long.
Friends knew that the couple was trying to make their marriage work but couldn't. According to Mumbai Mirror, Mehr learnt in 2017 that Arjun and Sussanne were still meeting secretly and were close friends. 
"She was traumatised as she had believed Arjun when he said he was a changed man and that everything would be fine," the source told Mumbai Mirror.
And that looks like the final straw in their already troubled marriage as the couple announced their split yesterday after two decades. 
In 2014, Sussanne Khan, who had then ended her marriage with Bollywood star Hrithik Roshan, was forced to defend her relationship with Arjun Rampal. 
"Arjun and Mehr are friends and have been for years. To poison a relationship such as this is malicious behavior. I have, with Mehr, earlier stated in the same paper that there is no truth to the claim that Arjun and I are anything more than friends," she had told First Post. 
On May 28, Arjun and Mehr announced their separation via a joint statement. "After a 20-year-long beautiful journey filled with love and beautiful memories, we would like to share, that all journeys have different paths. We feel that it is time for us to move on to different destinations henceforth. We have always been solid when it has come to us, we will continue to be solid for each other and our loved ones, as we embark upon a new journey," read an excerpt from their statement. 
"Both of us being extremely private people feel strange to be making this statement, but such are the circumstances of our lives. Where the truth can get distorted and lost. We are a family, our love for each other is forever intact and we shall always be there for one another and most importantly, for our children Mahikaa and Myra. We would therefore appreciate our privacy through this time. Thank all for their support. Relationships can end, but love lives on. We won't be commenting on this any further."
