Shanna Moakler's most recent split
from husband Travis Barker has been "devastating," she tells PEOPLE.
"We separated, and for me it's very disappointing," Moakler, 32, admitted while attending the HER Energy Drink Luau, a benefit for the Nicole Brown Foundation at L.A.'s Playboy Mansion on Saturday. "I consider him the love of my life."
Looking fit, fabulous and ready to move on, the former Miss USA and Dancing with the Stars
hoofer says, "I think the demise of a marriage is like a death, and there is a mourning that goes with it. It's devastating."
Still, Moakler expresses no regrets about her efforts to mend her broken marriage to the Blink 182 drummer. The couple, who appeared on MTV's reality series Meet the Barkers
, married in 2004
, divorced in 2006
and reconciled briefly
this year before calling it quits again in July
"I know that I gave it 100 percent, and I really tried," she says. "Where it's going to go I have no idea."
Despite showing up at the skin-baring bash and fashion show at the Playboy Mansion – which was also attended by Denise Richards
, Kim Kardashian and a bevy of bikini-clad beauties – Moakler is not jumping back into the dating game any time soon.
"I'm kind of getting back to myself, my work and things like that," she says. “I'm going out with my girlfriends and going to fun places like this, trying not to think about it."
She adds, with a laugh, "Even my Dad was like, 'You are not allowed to date for three to six months.' I don't think I should either."
Instead, besides appearing in an upcoming episode of HBO's Entourage
and hosting The CW's beauty pageant reality series Crowned
, she's focusing on what's best for her children: Atiana, 8 (fathered by ex-fiancé Oscar de la Hoya), Landon, 3, and Alabama, 19 months. Barker, she says, is helping with the kids, too.
"I think, more than anything, Travis and I have the main goal of trying to be the best parents for our children that we can be. So whatever that entails, we'll definitely do 100 percent."
