Olivia Wilde
is seriously wild for her fiance, Jason Sudeikis!

The actress gushes about her "Saturday Night Live" beau in the April issue of Marie Claire, talking love at first sight, having children one day and her humanitarian passions.

While the 29-year-old has been married one time before, she believes her ex-husband, Tao Ruspoli, brought her to Jason.

"I had grown up with Tao; we had just drifted. I felt I had something to prove. If you fall off a horse, you get back up. I am not a quitter. I hung on for as long as possible, until it was more hurtful to stay ... I'm so grateful for the pain and the heartbreak. It gave me the courage to leave and brought me the great love of my life," she says.

Wilde met her "great love" on the season finale of "SNL" back in 2011 -- and while they were both seeing other people at the time, there was an instant spark that couldn't be ignored.

Even though the brunette beauty felt that immediate attraction ... she still had her own insecurities adding, "I thought 'He won't be interested in me; I'm not a contender.' He was so cool, so funny — I was such a fan of his and had always fancied his speed and his intelligence."

After just one date, Wilde confesses she was in love! "I felt like fresh meat at the market ... I thought, I'm not beautiful enough or his type. I couldn't wait to sit down and hear him talk. On our first date, in New York City, we closed the restaurant down at 2 a.m.! He didn't kiss me, and I was madly in love. I was overwhelmed."
