After almost a year of silence, LeAnn Rimes opened up to PEOPLE about her relationship with Eddie Cibrian, her divorce from Dean Sheremet and how she never thought what she was doing "was okay."

Rimes and Sheremet ended their 7-year marriage last year after news of her affair with Cibrian broke. Cibrian was also married at the time; he and model Brandi Glanville married in 2002 and have two sons together. They too filed for divorce last year. Rimes and Cibrian are currently in a committed relationship.

"I take responsibility for everything I've done," LeAnn tells PEOPLE. "I hate that people got hurt. But I don't regret the outcome. It was very emotionally driven. I never once thought what I was doing was OK. I was out of balance. My marriage was out of balance. There was something missing. The hardest thing to hear is someone call either of us a home wrecker because we didn't walk into a perfectly happy marriage and ruin it. I don't know what the future holds, but I know it holds Eddie. I'm really happy. I've moved on, and I hope there can be some forgiveness and acceptance."
