It's been a long and very public few weeks for Jennie Garth since announcing her divorce from Twilight actor Peter Facinelli, her husband of 11 years.

From addressing cheating rumors involving Facinelli, 38, to Garth, 40, coming to terms with the split through a People magazine interview, the two have not been shy to discuss their divorce in public.

It's not something I'm dying to talk about, but it's something that's going on in my life and I'm not ashamed to talk about it, Garth said on The Ellen DeGeneres Show, in an episode airing Friday.

If anything, Garth said, talking about her divorce has actually helped other people get through their own break-ups.

The Beverly Hills, 90210 alum first met Facinelli on the set of a TV movie in 1996. Five years later, they were married and have been raising their three young daughters ever since.

We're still a family of some kind. We're still so committed to being there for our girls and that's the most important thing for us, Garth told DeGeneres.

Two weeks ago, Facinelli appeared as a guest co-host on Live! With Kelly, where he also talked about keeping the family together in the wake of the divorce.

[Jennie] will always be in my life. I love her, we're just going to have a very different relationship . . . we're very dedicated to being great parents, he said.

It's very painful to break up with somebody, especially after you've been together for 17 years and have kids, he added.

Garth and Facinelli first announced their split on Mar. 13.

While we have decided to end our marriage, we both share the same deep love and devotion to our children. We remain dedicated to raising our beautiful daughters together. We ask for privacy and respect during this time, they said in a joint statement.

The following day, Garth and Facinelli released yet another statement, this time addressing a cheating rumor that claimed that Facinelli was having a torrid affair with a woman he met on the Vancouver, Canada set of Twilight.

There are rumors out there which are completely untrue and hurtful to our family. We just want to make it very clear -- there are no third parties involved, the couple said.

Facinelli officially submitted divorce papers to a Los Angeles County Superior Court on Mar. 28, citing irreconcilable differences along with a request to have joint custody of his daughters.
