Ben Affleck, Jennifer Lopez divorce may test Jennifer Garner's own love life: expert

Jennifer Garner and John C. Miller are notoriously private about their relationship, but experts believe their hands-off dating approach sends "red flags."

"However, it is a red flag that there have been a lot of insiders coming out about his nonsupport of the very special relationship that Ben and Jen have." "It kind of shows, even though he's not outwardly displaying not being a supportive partner, I would say that when somebody is so secretive about a relationship, it's giving nonsupport. It's giving unsupportive." Tracy Wright is an entertainment reporter for Fox News Digital. Send story tips to Tracy.Wright@fox.com.

While mostly elusive and rarely spotted together, Miller and Garner stepped out for a date night in Malibu upon her return home, but celebrity matchmaker Alessandra Conti warned that Miller may be uncomfortable with what's to come for Garner now that Affleck may be in a new crisis mode.
