"I’m not saying everything’s okay," says Bergman, 34. "I'm still angry. I'm still mad. I am still hurt. "
The couple, who are parents to, Jaden 8, and Bella, 8 months, have been working through their issues for the past year with the help of therapy.
"It took a crisis, it took infidelity to get us off our asses and work for what we want," admits Bergman. "We do the best we can. That’s all we can do."
Boreanaz has taken responsibility for his actions and says he hopes the couple can recover the strong relationship they once had. "When we got married we had an unbelievable foundation that we’ve never forgotten," the actor, 40, says. "But it’s been damaged."
Their future may be unknown but both are committed to moving forward – slowly – now that the past secrets are on the table. "What’s working for us [is] taking our time," says Bergman, "moment to moment, day to day."
