<human>: So, long story short, we kissed, and actually, everything was fine afterwards!!! Next day at night, though, she seemed to be awkwarded out after I mentioned it through chat. She stopped answering my messages afterwards. I gave up after a couple of days. 

I told myself I would wait until I saw her again in person. But when I went to this monthly event she always goes to, she wasn't there. I grew paranoid that she was avoiding me (totally possible she just missed it though). She has not unfriended me on Facebook, but her icon taunts me. I don't want to send anything just to get ignored again, I don't want to seem needy (even though I'm pretty sure I already gave that impression).

The silence will be two months old by next friday (this also happens to be the date of this monthly event. I'm not sure if she will go). I want to think I'm doing fine in life otherwise. I solved certain problems, I started several projects... I live on. 

But I can't stop thinking about her, no matter what I try. I make peace with the fact that there's nothing wrong with me liking her and her not liking me, but I am still confused, since I know absolutely *nothing* about her feelings or her thoughts. Should I talk to her? Should I let her be? Does it even matter at this point? Did I screw up in waiting this long? I waited as long because I meant to cool down, but I'm not getting any less restless, and this is getting uncomfortably long. Thoughts?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Kissed this girl two months ago. She stopped responding with no explanation. Tired of waiting. Should I remain silent or should I try reaching out?
