After 10 years of marriage, Tom Arnold and Ashley Groussman are going their separate ways.

The True Lies actor, 59, confirmed to PEOPLE that he and Groussman — who share son Jax, 5, and daughter Quinn, 3 — have split, explaining, “It’s not super fun but it’s okay.”

“It’s the right thing,” Arnold said. “We tried to make it work. It wasn’t a big dramatic thing. It wasn’t all of a sudden. We definitely grew apart. It’s been a rough couple of years.”

Though there have been tough times, Arnold focused on the positives.

“Because I’m a father, I genuinely have the best life I’ve ever had and I’m so grateful to Ashley because I would not be a father if not for her,” he said. “We had many good years together. Everybody has one life. People change. I support her living her life and I don’t want her to feel any guilt and I am very grateful for what we had.”

This was Arnold’s fourth marriage. He was previously married to Shelby Roos (from 2002 to 2008), Julie Armstrong (from 1995 to 1999), and Roseanne Barr (from 1990 and 1994).

Arnold and Groussman, a home organizer, met through mutual friends in April 2008. The two became engaged the following March at Arnold’s 50th birthday party.

“I’m the luckiest girl in the world!” Groussman added at the time.

More than 75 family and friends attended their November 2009 wedding ceremony at Shep and Renee Gordon’s home in Maui, Hawaii — including actor Dax Shepard, who served as Arnold’s best man.

RadarOnline was first to report Arnold and Groussman’s breakup.
