The 'Blurred Lines' hitmaker was very open about his desire to win back the 'Baggage Claim' actress, who split from him last month after eight years of marriage, but he now plans to focus on being a ''great friend'' to her and writing songs for his next album.
The 37-year-old star told PEOPLE.com in New York City on Tuesday (25.03.14): ''We're both doing well. We're both very happy right now - much happier. Everything about this moment in my life - this amazing year I just had and what I'm going through personally - has actually ignited some of the best writing I've done in a long time.
''Whatever everybody's wondering about, they're going to hear it all in the album.''
Robin, who has son Julian, three, with Paula, also said the actress was very touched when he paid an emotional tribute to her at one of his concerts recently.
He said: ''My music is very honest about what I'm going through and my songs are about my life. And my relationship with her was 21 years of my life, so I just thought it was important to me to let people know how much she means to me.''
He added: ''She loved it. She thought it was the sweetest thing and very romantic, and I've always been a romantic guy that way.''
Asked about his plans for the rest of the year, he said: ''Just to be a great father and hopefully write some great music, put on some great shows and be a great friend to Paula.''
A source previously revealed that Paula was having second thoughts about filing for divorce, but is yet to feel convinced by Robin's efforts to prove he can be a good husband.
Though the couple insisted their split was mutual when they announced their separation, it was subsequently reported that Paula told her spouse she wanted a divorce and Robin did everything he could to get her to change her mind.
