Robin Wright Penn, whose relationship with Sean Penn has been on-again, off-again for the several years, says she has no plans to reconcile with the actor.
"I'd been stagnant," the actress, best known for roles in The Princess Bride
and Forrest Gump
, tells More
magazine for its September issue, on sale Aug. 25. "I think I've always been waiting for things to happen. Now I'm like, 'I'm okay – I know the direction, whoever's on board can go with me."
One person who won't likely be onboard is Penn. Together since 1989 and married in 1996, the couple endured a roller-coaster relationship only to file papers of legal separation
not once, but twice – only to patch things up
again as recently as May.
But that was then, not now. "I hit that crossroad a while ago," Wright Penn says. "I know what I don't want."
What she does want is to re-activate her career. "There's no limbo anymore," she says. "There's no time. I'm too old for this s---."
Regarding her much-discussed marriage, friends tell More
that what the couple had was a "peculiar chemistry. For her part, Wright Penn tenders no regrets.
"I, we, have two amazing children we raised together," she says. Daughter Dylan Frances, 18, is headed off to college, with son Hopper Jack, 16, preparing to follow suit – which will leave mom with an empty nest.
"At least twice a week, I pull over and sob," she says. "My baby is leaving. It's an emotionally full time, but it's not sad. I can't wait for Dylan to go [out and] live. That's what makes me cry."
