If you want to know the secret to a long and happy marriage then just ask Mark Ruffalo, 50, and his wife, Sunrise Coigney, 46. The Hollywood A-listers have been married for close to 20 years and Mark credits their successful union to always “being honest with each other.”

According to Life & Style magazine, Mark said that being honest with his wife has only made his marriage stronger. He also credited intimacy as another reason why they’ve been married for so long. “Sharing fantasies and our desires and being intimate, emotionally,” he said.

Mark’s ideal date night with Sunrise is not too fancy either. He simply said, “locking ourselves in the bedroom,” is the best way to spend a night away from their kids, Keen Ruffalo, 17, Bella Ruffalo, 13, and Odette Ruffalo, 11.

Mark previously met his wife when he was still just a struggling actor. Thanks to her unwavering determination, she helped him reach unprecedented success in Hollywood, and in return, Mark never left her side.

“I must have auditioned 800 times without landing a part. I was tending bar at Chateau Marmont [in LA], and I’d see Johnny Depp and Nic Cage hanging around, hugely successful, while I was barely making a living,” he said in a previous interview with Bustle. “I was becoming angry; I decided to quit at least four or five times in my 20s.”

“I was living in a dump and didn’t even have a driver’s license or a credit card. She thought I was a mess, but she believed in me and kept encouraging me,” he continued. “I don’t know if I would have made it without her.”

Now Mark has a booming career and is widely recognized as The Incredible Hulk from The Avengers franchise. And no matter what role he takes on, he will always have Sunrise standing by his side and supporting him — what an incredible love story!
