OP, leaving her on Valentine's was a real dick move. You fucked up, and your current feelings are deserved karma.

I'll add how you made sure to add "less attractive", btw. The whole story did not need that qualifier.

What this makes me feel is you haven't found another girl at that level and are feeling it. Its attraction and regret, nothing more, and that girl is well rid of you.

Move on and try not to be as shitty next time.
