Britney Spears is still under a conservatorship and it is reportedly that same conservator that ended things between her and her fiance Jason Trawick.

 According to RadarOnline.com, Britney wouldn't have been able to handle the breakup in a rational way -- so Britney's dad, Jamie, was the one who orchestrated the entire split.

A source said, "It really wasn't Britney's decision to announce the split last week, it was Jamie who made the call. Jason wanted out, and in the fragile state that Britney is in, it's not like he could have a rational conversation with her about it, so it was really between him and Jamie. They decided how the relationship needed to end and how to go about the technicalities, such as removing Jason from the conservatorship, when he would move out and how to announce the split. Britney was left out of everything and really didn't even know what was going on. Jason and Jamie wanted to make sure that Britney didn't lose it, so they had to water things down for her a bit. She knows that the engagement is off and that Jason has been removed from the conservatorship, but she still hasn't exactly grasped yet that the relationship is totally over."
