To escape having to tell her boyfriend to his face that she was breaking up with him, she got her girlfriend to do it.
As I recall, Candace volunteered to do it (10/15), showing intent on her part. And if you look carefully at the next few strips, her body language shoes that she’s definitely coming on to Anthony (no accident — Lynn’s intent). There’s some truth in all the viewpoints I see on this page, but I think Elizabeth’s hurt comes mostly from the betrayal of trust she feels.
