The 'Get Her Back' hitmaker, who was dumped by the actress after eight years of marriage in February amid rumours of cheating and has poured his feelings into his new album, 'Paula,' admits his efforts to win her back might be a waste of time.
The 37-year-old star told 'Good Morning America' today (02.07.14): ''I actually have no idea what I'm doing. I'm just kinda flying by the seat of my pants on this one.''
He added: ''I just wanted to make something artistic out of a very difficult period.
''When you lose the love of your life you don't have much to hide anymore.''
But Robin, who recently claimed he hasn't seen his estranged wife in four months, is prepared to be just friends with the 38-year-old actress in the future.
Asked about the final track about friendship, 'Forever Love,' on his album, he said: ''The album... I didn't want it to be all depressing. I didn't want her to listen to it and make her sad only. I wanted there to be moments where she had hope and positivity that her and I can both still have a great life, no matter what happens, and we'll be great friends and great parents.''
He also revealed that the idea for his latest music video, 'Still Madly Crazy,' which features children lip-synching the ballad at a wedding, came to him while he was looking at photo albums from their wedding.
He added: ''We were childhood sweethearts, so you know she's the best person I've ever met. So I just thought the least I could do would be to devote an album to her.''
The heartbroken singer, who has four-year-old son Julian with Paula, also encouraged his fans: ''If you've got a good woman take care of her guys.''
