The former Genesis star – who has been married three times, to Andrea Bertorelli, Jill Taverman and Orianne Cevey – admits he would have given up his career had he known his determination to be a success would "cost him so dearly".
He said: "In the 70s, Genesis did three American tours a year, three European ones and a trip to Japan. My first wife, Andrea, told me if I toured like that, the marriage wouldn’t last. When I got back, she'd left me. If I'd known touring would cost me so dearly, I wouldn’t have done it."
The 59-year-old star is now trying to live a quieter life, and spends his days in Switzerland so he can see his sons Nicholas and Matthew – from his marriage to Orianne, which ended in 2007.
He said: "I'm happy being at home. I've said yes to things all my life. Now I'm learning to say no. I stay in Switzerland, as Orianne is there, and we share the care of the two boys.
"I'm not totally happy being on my own, though. I'd rather still be married and I think Orianne feels the same. She's re-married, but we have a fantastic relationship.
"I get on well with all my ex-wives. They also get along with each other and my girlfriend. It's a picture I never thought I'd see, but it works well."
Phil is currently dating US newsreader Dana Tyler, but admits he is fearful of getting wed for a fourth time.
He explained in an interview with the Daily Mail newspaper: "Will we get married? I don’t think so. I have a commitment, but I don’t see the point. I don’t like being away from Switzerland and the boys for too long."
