After 10 years of union why Ben and Jen split?

Fans and the film fraternity are very morose with the news of their split after 10 years of happy nuptial bond. Yes, we are talking about the hottest Hollywood couple Ben Affleck and Jennifer Garner. The duo started their courtship since the days of the Daredevil shoot almost a decade back and later on the “bad boy” Ben was the chosen best man for Jennifer after a serious of relationship of his with celebrities like Gwyneth Paltrow and Jennifer Lopez. He was even a drug addict and a gambler in the rehab at that time but withstanding all odds, both Ben and Jen tied the knot and consequentially shared parenthood with the birth of their three kids- Violet 9, Seraphina 6 and 3 year old Samuel. 

Recently, on June 30th the couple calls it quit and they are not “together” anymore. Per sources the both are facing tough time as it’s hard to part after being in a relationship for so long. Even for a year or so Ben and Jen were consulting different therapies but according to many celebrity tabloids, none of that worked out and finally they are calling it off. 

Right now, Ben has been shifted to a guest house and found tired in a promotion of his upcoming superhero combo- “Batman V Superman- Dawn of Justice” arranged by Comic Con in San Diego. Jennifer is now busy shooting for her next. 
The split couple has requested privacy as it is really a tough time for them and right now their top priority are the kids.
