MANILA - Now that she is engaged to boyfriend Paul Jake Castillo, Kaye Abad gamely revealed on Monday that she was the one who broke the hearts of her two exes.

"May isang ako 'yung nasaktan; dalawa 'yung ako ang nakasakit," Abad said in an interview on "Magandang Buhay" on Monday without identifying her two former boyfriends.

Before Castillo, Abad was in a relationship with Parokya Ni Edgar frontman Chito Miranda, who is now married to actress Neri Naig.

Abad also dated Guji Lorenzana, who got married just this year.

Years ago, Abad once dated "Tabing Ilog" co-star John Lloyd Cruz.

"Ang hirap, ang hirap-hirap kapag ikaw 'yung nakakakasakit. Parang feeling mo ang sama-sama mong tao," she admitted on Monday. "Pero siyempre, sabi nga ng kaibigan ko, hindi pa nila maiintindihan 'yan ngayon na para din naman sa kanya 'yang desisyon mo, na mas makakabuti talaga kung hindi na. So I think okay na silang dalawa ngayon -- may asawa na sila, masaya na silang dalawa."

But Abad said she has no regrets about her past relationships. "Feeling ko mas makakabuti talaga para sa amin," she said.

Abad said one of the lessons she learned about relationships is that both parties have to be open to each other.

"Dati kasi nung bata ako mahigpit ako, selosa ako, tapos kapag may party siya, 'di ko papayagan. 'Yun 'yung natutunan ko -- plus sa mga friends din -- na kahit na paghigpitan mo, kung gusto niya ay gagawa at gagawa ng paraan, maitatago at maitatago niya," she said.

"So ako natutunan ko na maging open na sabihin mo sa akin kung may crush ka o may kay text ka, okay lang. Kasi once na mahuli kita at itinago mo sa akin, ibig sabihin ay sini-seryoso mo 'yan para itago mo sa akin kasi open ako. Kung may crush ka normal lang naman 'yung crush, so 'yun maging open lang," she explained.

Abad is now busy preparing for her wedding with Castillo, who asked for her hand in marriage during her 34th birthday last May 17.
