What happens is the boyfriend loses interest in the girl, but the girl gets some stupid chump to hang out with her, and then her boyfriend gets jealous, and the girl and her boyfriend fall in love again, since this is what the girl wanted, to use some chump so she can be with her true boyfriend again.
