There's a slim chance that Ben Affleck and Jennifer Garner will be back in each other's arms soon.

This, after the "Alias" star reportedly admitted that her husband is back to his old, errant ways, according to "In Touch" (via "OK!" magazine).

"Jen believes that Ben's been drinking and picking up women behind her back," the source allegedly revealed to "In Touch."

The 43-year-old actress completely lost faith in her husband accordingly when rumors broke out that he was having an alleged affair with their kids' nanny Christine Ouzounian.

But despite the "Batman v Superman" star's misgivings, the "Elektra" star thought that she could still change her hubby's "behavioral" problems, according to the source.

"Ben was doing so well," the source said. "He was going to therapy twice a week and attending church with the family."

However, at this stage, Jennifer Garner now apparently reportedly feels that she has been irrational in thinking that she and Ben Affleck could reconcile their differences.

"This was Ben's last shot to make things right and he didn't," the insider shared. "She's done fighting the same fight."

Meanwhile, the "Argo" actor appeared stressed out on the set of his latest film "Live By Night" after reports came out that her ex-partner allegedly went out with a mysterious "gentleman," according to Radar Online.

The "Catch Me If You Can" actress, however, was not alone as she was said to be accompanied by her children during the Halloween date.

Earlier this week, Jennifer Garner was purportedly spotted wearing an engagement ring. Could this be an indication that there is still a chance for her and Ben Affleck?

The "Sum of All Fears" actor announced his divorce from the "Juno" star this summer after 10 years of marriage.

The couple's marital woes began when rumors surfaced that Ben Affleck was engaged in multiple relationships - including Ouzounian - which resulted in his eventual split with Jennifer Garner.
