<human>: Condense the text into a few key points

There is a whole story, that if someone wants to ask specificity to I can. There was definitely mutual attraction. Found out via a reddit post she responded to that she is seeing someone, so she doesn't know I found out probably why she was acting distant.

What do I do, do I let her know I found out? It's funny because I'm hurt sure and depressed about it because I've liked (I'll go with loved her) for a really long time. But due to timing and situational things nothing ever really progressed. Also she is geographically distant, so we don't see each other much at all.  However, finding out was more of an 'A-Ha' more than anything.  I really adore this girl and I've missed an opportunity with her a long time ago out of misunderstanding.  But she just doesn't respond.
<bot>: found out girl is seeing someone, why act cold and cause more problems with having me push to figure it out then just say it?
