I met a girl a while back and I won't deny my heavy investment in her, nearly a unicorn however she got drunk and kissed a dude so I dropped her immediately.

I don't regret my decision, I won't look back on my decision and I won't sit here wondering what might have been. I will not tolerate that behavior. In the meantime I've met some other women, furthered some of my goals, continued progress at the gym and have all around been doing all I can to keep busy.

Complications arise though, as she is still stuck in my thoughts, there is no reason for her to be and I decidedly do not want her to be there. I made my decision, she wasn't the illusion that I projected onto her and I'll be a lot better off without her. So why the fuck can I not stop thinking about her, has anyone had a similar situation and what can I do about it?
