Jake Gyllenhaal Explains Why He Hasn't Gotten Married

— -- Jake Gyllenhaal is one of Hollywood's most eligible bachelors, but it's a title he's excited to shake.

The "Southpaw" star is hoping to get married, he told Howard Stern during a visit to his Sirius XM radio show.

"There are a lot of beautiful women and there are opportunities," he acknowledged, "but... I believe in monogamy. I believe in, when you meet somebody who's right, it'll be right and you'll stay there."

Gyllenhaal, 34, told Stern that he's been in love two or three times in the past, but he's not in love now. He blames himself for those relationships not turning into more serious unions.

"I think I probably got scared," he admitted. "But I also think at some point, I think you just decide to grow up."

If and when he does tie the knot, the Oscar nominee said he will look to the relationship his sister, Maggie, has with her husband, actor Peter Sarsgaard, as a model.

"They're definitely a standard for me... based on their kids and how great they are with their kids," he said.
