On this occasion, all blame lies at Casey's feet. She is no longer unaware of his feelings for Jasmine, his actions have spoken louder than words ever could to indicate she is second choice by a long way, and he in most clips I have seen, is usually facing away or avoiding eye contact whilst she drapes herself over him, offers blowjobs and tries to make him see that he loves her. He is not obliged to turn her down if she offers it up, and from what we can all tell, he is very unlikely to show restraint. She better not turn the waterworks on when he loses interest because Jasmine/someone newer/fitter becomes available in the future.
