The thought of revenge is what's propelling Jennifer Garner onward as she deals with her messy breakup from husband Ben Affleck, at least that is what unnamed sources say.

"Jen's facing a future on her own, but she refuses to let Ben win," a source told Radar Online. "She knows success is the best revenge on Ben and she dreams of trumping his Oscar win with one of her own one day."

Garner and Affleck recently announced they were pulling the plug on their 10-year union after rumors spread of his involvement with the former nanny of their three young children. All the details surrounding the nature of Affleck's relationship with Christine Ouzounian remain a bit murky, but it clearly seems the last draw in ending his marriage with Garner.

Still, Affleck has denied being romantically involved with the much younger Ouzounian, including an Us Weekly magazine report that claims the two dated over a 10-month period when he and Garner were separated.

Since their public split, Garner has largely immersed herself in her work and is currently filming two movies, including "Miracles from Heaven" in Atlanta. In addition, Garner is also rumored to have another six flicks in various stages of production.

But Garner knows work along isn't the total answer and there are other ways for her to show just how much she's grown.

"She's even more determined to build up her image and her trip to visit the sick kids in the hospital recently is just the start," a source added. "She also really wants to increase her circle of girlfriends and would love to follow in Angelina Jolie's footsteps with more philanthropic work."

As for Ouzounian, The New York Post recently published a photo of her jetting off on a private airliner with Affleck and New England Patriots star quarterback Tom Brady bound for Las Vegas.
