I despise her with a passion, actually the only one I don't have a reason to hate is Lacey.
She told him, she was only with him for his status and sex. Admitted she had been cheating on him since they got together, and JImmy loved her. So much.
Brian has groupies. But I don't blame him, Michelle is not very nice to him... and Brian has even called her a 'spoiled brat', and Michelle also cheats, and uses Brian, even told him to get over Jimmy.
And no, Leana and Jims were only engaged but that was broken off before he died... Leana is a reason of why Jims is no longer with us.
