Their marriage may have moved past the scandal now, but a friend of Abedin's tells CNN that upon Weiner's confession Abedin was furious, and seriously considered ending the marriage.
Upon reflection, the friend says, she felt that taking their son from his father was not what was best for him, and ultimately decided to continue with therapy in an effort to heal their relationship.
In his e-mail to supporters Wednesday, Weiner said the exchange was "a terrible mistake that I unfortunately returned to during a rough time in our marriage."
The verdict is still out on whether Weiner will survive the latest firestorm. Polls taken over the past several weeks have shown Weiner either slightly ahead of his closest rival for the Democratic mayoral nomination, Quinn, or trailing her in second place.
"He's been campaigning asking for a second chance. Now today he's asking for a third chance," CNN contributor John Avlon said Wednesday morning. "That's fundamentally different in what the voters are being asked."
Ana Navarro, a Republican strategist and CNN commentator, said Weiner's latest admission will put him even further under water with women voters.
"I don't claim to be a thermometer for the women vote, but I can tell you it'd be hard for me to vote for a guy who's now made his wife endure this kind of public humiliation," she said.
