A source close to Garner said, "It’s not an easy situation for Jen," and then added that she is staying in "mama-bear mode" for right now, according to a report from People.

The source also revealed that Garner anticipated Affleck would go public, saying, "She knew it would happen soon. Ben just can’t be alone."

Shortly after it was reported that Affleck had a new girlfriend, it was widely reported that he had been cheating on Jennifer Garner with her.

According to a source, "Ben and Lindsay [Shookus] started their affair in 2015. They were not casually dating — they were having a full-blown affair," as reported by The Daily Mail.

The source continued, "They were sleeping together, sending each other cute texts and meeting up whenever they could."

It's also reported that Jennifer Garner and Kevin Miller, Lindsay's ex-husband were "devastated" when they discovered the affair a few years ago.

On the contrary, however, a source close to Affleck claims that this is untrue.

"Lindsay was not what led to the end of their marriage. They had a ton of other problems," the Affleck source said.

The new Garner source refutes this, saying that "it would have been easier for Jen if Ben would have just dated someone that Jen wasn’t familiar with."

Still though, a separate source reveals that Garner is doing fine, saying, "“Of course there are issues given it was a major affair, but Jen is her own woman and is completely fine. Nothing is new for her here."
