Sandra Bullock's husband is "heavily targeted and pursued" by women, a source tells PEOPLE. "Those girls throw themselves at him."
The source adds that temptations were around before tattoo model Michelle McGee met James and came forward with allegations of a steamy affair with James. On Thursday James called the "vast majority" of allegations "untrue and unfounded," but apologized to his wife and children for "this whole situation."
According to another source, James had been hanging around "people that [Sandra] may not have necessarily approved of – women."
Still, that source tells PEOPLE that the The Blind Side Oscar winner always saw the best in her husband. "She trusted him," says the source.
