Most of us probably saw this coming from a mile away, but not Jennifer Aniston who's been blinded by love. Notorious love-em-and-leave-em playboy John Mayer has reportedly broken up with Jen. The couple initially decided to spend some time apart, before making the split official earlier this week.

Jennifer has been unable to find love since her divorce from Brad Pitt four years ago. News of the split comes just weeks after the two were rumored to be considering marriage.

According to a source, John, 30, "took the decision to end things as he felt he just wasn't ready for the level of commitment that Jennifer deserved."

The source also said that Jen, 39, "didn't want to have kids or marry this year, but she did want to set a timetable for their future together."

"She also wanted him to assure her he would cut down his tours in the future when they did eventually have children," said the source. "Initially, Jennifer was furious when he told her of his decision but now she's simply sad - not to mention a little heartbroken.

The couple hadn't even been dating a year, and she's already demanding he give up his music for yet-to-be-born children? Therein lies the problem.
