Halle Berry is finally in a good place after a difficult split from Olivier Martinez.

“I just feel happy, you know? I’ve arrived at a really good place once again, that’s always good news,” she recently told Extra. “Down time, dark times, don’t last forever — the sun is out again and it feels great.”

Nearly one year after she filed for divorce from Martinez, the former couple have continued to spend time together and even go on family vacations with their children.

In a document filed Sept. 1, the L.A. Superior Court court clerk warned the couple that if they don’t take any action soon on their divorce filing, it could be dismissed.

Despite rumors of a reconciliation, a source close to the couple tells PEOPLE that Berry and Martinez are not back together. “Nothing is happening, no real change,” says the source. “She definitely has no interest in getting back with Olivier unless his temper and controlling nature change. And there’s no indication that either will, so it seems that they will remain separate.”

The Oscar winner also opened up to Extra about how she celebrated her 50th birthday. “Privately. It was very small. I’ve never had a birthday party, so it wasn’t a big extravaganza; it’s not how I do it,” she said of her 50th birthday celebration in August. “I was with my family, people I loved, it was a really good day. I’ve never defined myself by that number, so it was a really good day.”

As for her kids, Berry told Extra that Nahla, 8, and Maceo, 3 are “fantastic.” Watching them grow up so fast, Berry said, “Time stops for no one, nothing.”On the business side, Berry is starring in the upcoming thriller Kidnap hitting theaters in December. She also recently made a cameo in Kevin Hart’s new standup movie, Kevin Hart: What Now? “I love that man! So much fun,” she said of the comedian. “So much fun. It was a chance to sort of play with comedy a little bit. Who better to do that with than Kevin Hart, right?”
