ok i do agree with the other posters, but heres my little take on it.
i think its unfortunate that you may feel that love is an unfortuante experience. Its like life itself. In that, the lows of anything are there to justify or give the true meaning to when we experience the highs in anything. The best things in life come through ourselves overcoming some kind of hardship or low.
"That which does not kill us, makes us stronger"
I also believe in that its "better to have loved and lost than never to have loved at all". You should think about that, do you think it'd been better if you'd never meet her or talk to her. Given you seem to still be reflecting on it now, it seems that it did touch you in some special way, hopefully for the better.
Also try to think about the good memories you had with her, other than anything negative. Because you can't spend your time redigesting past regrets, cause you can't change anything in the past.
good luck with your future endeavours
