Short story was dating this girl, we kissed etc, but she would never have sex. I heard she gave another guy a blow job so I stopped going out with her.

She has been trying to ask me out but I'm not interested in her right now.

Yesterday she called me asking for job advice, I am a bit of an expert in job interview and how to do well. She asked me, part of me wants to help, I help all fellow students as the job market is tough, but part of me hates her as she was kissing me but sucking other dick.

What would you guys do?
