Your ex-boyfriend. He was an absolute scumbag while you were dating. (He'd forget promises without a second thought, cancel at the last minute constantly, prioritize his friends over you, stay way too close to other girls, and casually call them cute.) After the breakup: He realized how kind you actually were. (You always respected his space, told him it was okay when he forgot promises, and never tried to control him—yet you still made sure to tell him you loved him.) If he manages to win you back, he intends to treasure you above all else, keep every promise, and have eyes for no one but you.
