Despite Robin Thicke's pleas of forgiveness and the release of his apology album, 'Paula,' it appears that his marriage to Paula Patton is no more. Since their separation, Thicke has revealed that he hasn't seen his estranged wife in four months.

The 'Get Her Back' singer appeared on Hot 97's Ebro in the Morning to promote his new album and talk about the choices he made that led to the dissolution of his marriage.

"I try to keep most of that private, but, I haven't seen her for four months," Thicke said. "She the best girl in the world, a great mother and still a good friend. But I also want to wish her well and let her know that she's a great person and she deserves to have a great life."

The 38-year-old crooner admitted that stardom after the chart-topping success of 'Blurred Lines' led to some poor decisions on his part, which eventually ruined his marriage.

"Last year was really just kind of a blur in many ways, no pun intended,” he said. "Everything happened so fast and you don’t realize all the things that come with it. At this point in our relationship, the only reason we’re not together is because of the choices I made."

Thicke says that Patton hasn't heard the album and doesn't think it will bring her back to him.

"She hasn’t heard it," he said. "She’s only heard a few songs. And I don’t think she wants to hear it right now. I can’t speak for her, but I think space is an important part of any healing process."

So what was the cause of Thicke and Patton's break up after 20 years of being together?

"[Cheating] is not why we're apart," he states. "We're apart because we just couldn't be together anymore for a while. There's a hundred different reasons, there isn't just one. There's a long list. I changed, and I got a little too selfish, a little too greedy, and little too full of myself."

In the end, Thicke says 'Paula' is his self-help guide to becoming a better person.

"My music is my therapy," he says. "When I make these songs and I listen back to them, they make me feel good about myself because at least I'm admitting my faults and trying to become a better man, better person, better father."
