"We're cool. She's the best girl in the world, a great mother and still a good friend, but because we just weren't ever together anymore and I still had so much I wanted to apologize for and things I wanted to take responsibility for, so that's pretty much what the album's about," the singer said while describing his new record, Paula.
Thicke has said in the past he wrote the album for Patton, who announced in February the two were ending their nine-year marriage.
"Sometimes it's about her and sometimes I'm talking directly to her," he said about the tracks.
Despite multiple efforts to get her back, Thicke seems to be making peace with the fact that their relationship is over, at least for now.
"I also want to wish her well and let her know that she's a great person and she deserves to have a good life," he said, later adding. "Maybe a year or two off, we'll become our own people without each other and then it will be meant to be."
