Brad Pitt is reportedly still hesitant about whether or not he should marry Angelina Jolie. Pitt allegedly spoke to his grandmother, Betty Russell, shortly after the birth of his daughter Shiloh and told her he wasn't quite ready to marry again. "He is a sensitive soul who just wants to make sure he can keep his promise this time around," Russell says, referring to the fact that Pitt had failed his promise to his former wife Jennifer Aniston that they'd be together forever. "Brad has always wanted to have children and he is playing the father role very well," Pitt's grandmother says. "The family loved Jennifer. But he has got Angelina now and seems really happy with life. He's very close to Maddox. He confides little secrets to him."
