"I've had some post-traumatic stress disorder after Valentine's Day," the actor tells iVillage exclusively. "I broke up with two of my ex-girlfriends -- like long relationships -- on Valentine's Day. But it was healthy. It's hard to go through the day when you know that something's up. So you gotta address it."
Despite his past relationship issues, Tatum, 31, is now happily married to actress Jenna Dewan -- and he loves to plan romantic surprises for her. (Like taking her on an impromptu trip to Hawaii!)
But Tatum isn't the only one who knows how to be suave. His costar Rachel McAdams (who's currently dating actor Michael Sheen) says she's been on the receiving end of some pretty romantic gestures. "I was going backpacking by myself for the first time...I have a terrible sense of direction and I had no plans, and (my boyfriend at the time) was freaking out," the 33-year-old actress explains. "So he gave me a compass that was engraved and said, 'Never lose your way.'"
Watch our exclusive video interview to find out how Tatum would woo his wife if she lost her memory, and why McAdams thinks Valentine's Day is a lot of pressure -- "just like New Year's Eve."
