Casey Anthony splits from married boyfriend: He regrets leaving his wife for her

“Tot mom” Casey Anthony has parted ways with her married boyfriend — and the notorious former murder defendant is telling friends that she simply “grew tired” of the relationship.“She gets bored easily,” says a pal of Anthony, who became an international figure after the disappearance and murder of her 2-year-old daughter, Caylee.
