Ben Affleck gained 30 pounds following his recent split with Jennifer Garner.

Affleck reportedly gained a lot of weight due to stress eating, but the new eating habit was not about Garner, it was said to be about being a "bad dad," as per Celeb Dirty Laundry.

According to the media outlet, Ben's dad is an alcoholic and left his mom when he was just 11 year old. He was raised by his mom all alone and his dad rarely communicates with him until he got clean.

Experiencing being terribly lonely in the past, he doesn't want his family to go through the same fate. His worst fear is to become an "absentee father" just like his estranged dad. His fear and anxiety are said to be causing this new detestable eating habit.

Ben and Jen decided to push through the divorce but they both agreed that they will live together in the same property, so they could watch the kids closely. However, Garner reportedly changed her mind and "kicked him off their estate." So, now Ben is worried, that if his work will take him outside the country for quite awhile, the kid's might think that he is gone for good.

While trying to sort things out, Ben has been binge eating to cope with stress. He has already committed to directing as well as playing as the lead in 'Live By Night', and filming will start in November.

In addition, he's also committed to do 'Justice League.'  

He already knows that these upcoming projects will take a lot of his time , so it adds to his worries, knowing that the kids are already upset about the split.

After being married for ten years, the estranged couple announced the split in June. Though unclear what the real reason is behind the split, speculations has it  that among the reasons is his being a workaholic.
