Well, she got what she wanted. He branched out, got some confidence, focused up and got himself under control. And so why is she so concerned about him?
Like hell, this is what she told him to do. He was infatuated with her, she could've locked that little simp with the power to lay pipe like a Mario brother down but noooooo, she just had to let her baggage get in the way and chase him, quite literally, into another woman's arms.
Now he acts like what she treated him as, a f***boy. She wanted him at her convenience, well now he isn't hers alone. She's gonna have to deal with the consequences
