"I dated my husband for nine years, but while he was in the army, I cheated," she admitted (keep in mind that she is calling him her husband as a current title, not saying they were married at the time).  She continued, "When my husband was in the army, I dated another man for about a year and a half.  I told my husband that we should break up so I could focus on work.  Honestly, I was dating two at the same time."

However, she was ultimately caught.  Jung Joo Ri continued, "My husband dropped by home and I got caught when he happened to see a picture I took with the man I was cheating on him with.  He told me that he burned all of the letters I had sent to him in the army."

Well, now they're happily married with a newborn baby!
