Newly single Jennifer Garner wears wedding ring and looks somber on outing with children... as estranged husband Ben Affleck attends Comic-Con

Despite announcing their separation, estranged couple Jennifer Garner and Ben Affleck have been spending time together of late to put on an united front for their three children.

However on Saturday, the actress was spotted looking pensive during an outing in Atlanta, Georgia, with her three children - on the same day her estranged husband Ben Affleck made his first post-split appearance at Comic-Con in San Diego, California.

The 43-year-old - still wearing her wedding band - has kept busy filming her latest film Miracles From Heaven, amid new reports about their impending divorce, including the latest from People which says 'Affleck had a hard time meeting Garner's expectations of him as a husband.'

For her errand run, newly single Jennifer hid her makeup-free eyes with a pair of oversized sunglasses to cover her somber facial expression, no doubt due to the last few weeks.

The mother-of-three - who was joined by a nanny and her three children Violet, Seraphina and Samuel, cut a casual figure in a baggy white T-shirt and loose-fitting black shorts.

Noticeably still on her left hand was her silver wedding band. One day prior, Ben was pictured wearing his ring as well.

She carried only her mobile phone and Prada wallet as she picked up a greasy bag of food to-go.

Perhaps as a pick-me-up, the star treated herself to two lollipop candies on her way back to her vehicle.

Just one day after their ten year wedding anniversary, Jen and Ben made their split known to the public with an official joint statement.

'After much thought and careful consideration, we have made the difficult decision to divorce,' they confirmed to DailyMail.com on June 30.

'We go forward with love and friendship for one another and a commitment to co-parenting our children whose privacy we ask to be respected during this difficult time. This will be our only comment on this private, family matter. Thank you for understanding.'

The couple met as co-stars in 2001's Pearl Harbor, then fell in love on the set of the 2003 film Daredevil, in which they also played on-screen love interests.

Fast forward to the present, their decade-long marriage has reportedly been on the rocks for some time.

'When you're told you're not good enough, you start to believe it,' an insider close to Ben told People recently.

'Then where does that leave you as a couple? He couldn't deal with her expectations. Part of why this happened is her being controlling and unhappy.'

On the other hand, Jen's inner circle expressed their discontent towards the Argo director's efforts to continue on in their union.

'He underestimated the work that marriage requires. And once he realized it, he wasn't interested in it,' a source of Garner remarked.

Ben, meanwhile, put on a brave face as he made an appearance at the Batman V Superman: Dawn Of Justice panel at Comic-Con on Saturday.

During the event, Ben, 42, laughed away as he told fans how he had sought the advice of his predecessor, Christian Bale, on playing the Dark Knight.

The Batmen coincidentally ran into each other as they were shopping for costumes for their sons - Batman costumes, of course - in Los Angeles last Halloween.

'There he and I are standing in the Batman costume row and I said, "Do you have any tips?", Affleck recalled.

'And he said, "Make sure you can p*ss in that suit".'

Ben's Comic-Con turn comes after fresh reports claim tension between himself and Garner was mostly the result of the actor's inability to take control of his vices, mainly women, alcohol and at times, gambling. (A spokesperson for Affleck had no comment when contacted by DailyMail.com on Wednesday.) 

The actor had a 'candid conversation' with his wife where he admitted he had not been 'committed to the marriage in the last few years', People reported on Wednesday.

The magazine added his alleged womanising was a big factor in Garner's decision, with a source saying: 'There comes a time when enough is enough.' The publication reported that Affleck has denied being unfaithful.

Another insider was less delicate with their wording, alleging to Us Weekly: 'The reason they split is because of Ben's drinking and his infidelities.'
