He's following his dick and claims he's following his heart in some type of artistic sense.
Dumping your wife of 13 years and 2 children for a woman less than half your age makes you a shallow dirtbag, not an artist. Lots of 50yr old men would prefer to be poking a hot 23 yr old, but they stick with their families because it is the right thing to do.
In every interview I see with him Weller comes across more and more as someone with an extremely high self-opinion, incapable of serious introspection, which is a shame since lyrics from his first two solo albums were (IMO) particularly appealing because of their introspection.
Maybe I read it wrong ... but that's how the interview seemed to me. An interview with a man who is a legend in his own mind. Still love his earlier work though (Jam, some SC, first few solo albums).
