Sara hung her head. Just the fact that Heidi had been willing to forgive Tracey after what she had done was a testament to how much better a person Heidi was than Sara. She knew Tracey would be far happier with the quidditch star than with her.
"But I am!" Sara sobbed. "I'm a cruel, miserable and horribly selfish person." She shook her head. "Horribly selfish." she mumbled.
Sara was aware that that was exactly why she couldn't be with Tracey. Being with Tracey would mean that all her comforts and status would be put at risk and as much as she loved Tracey, she knew she couldn't risk that, if not for her than for her son. She knew even if she showed selflessness at some point, it wouldn't last forever. Sara didn't want Tracey to be hurt by that. "I'm so sorry." she mumbled.
