Why Avril and Deryck Called It Quits
"She married too young and she finally realized that," says a source. "Avril realized she needs her own life and needs to explore things without him."
The couple – who married in 2006, when Lavigne was 21 – announced their split on Thursday after weeks of speculation of trouble in the marriage. "I am grateful for our time together, and I am grateful and blessed for our remaining friendship," Lavigne wrote on her Web site.
Another source close to the couple, says the duo was having serious problems for at least six months. But, the source states, the split is "not about Deryck wanting a kid nor is she dating anyone else." As for rumors that Lavigne got close with pal Brandon Davis, the sources says, "There is no romance."
The couple, who plan to divorce, are no longer living together in their Bel Air home. "Deryck has left the house," says the source, but "wasn't kicked out."
Both Lavigne and Whibley, 29, lead singer of the band Sum 41, are currently working on new albums.
