<human>: Hello Relationship Advice, I have been lurking Reddit for ages but I have never had anything worth sharing anywhere. The reason I turn to you is because at this istant I'm drowning in self pity. 

Background:
I live in a mining town far away from major cities, my previous relationship collapsed due to the distance element, but the job is too good to give up and returning home was not an option. I recovered from that shitty break up, it was painful since I had to choose between a promising career or the girl I loved and lived with for the last 5 years, and met another girl at work. The girl from work is not like anyone I've met before, I was (I am) smitten, so I told her how I felt, she reciprocated. Subsequently we went on several dates, had multiple make out sessions and it was flipping awesome.

The Problem:
Last night I was ready to ask her is she'd like to be part of my life as my gf. So I did, she said I didn't know her enough to be asking her that, then proceded to make out with another dude right in from of me. Needless to say I was ( I am) crushed.

Advice?
Do I still pursue her? do I just get over it and re instate the fact that I'm crazy about her? Do I stop being such a retard and move the fuck on?

Thanks for reading,

Can you condense the text into three sentences or less?
<bot>: I like a girl, girl says she likes me back, everything is going well, I ask her to be my gf, she makes out with another dude, my jimmies get rustled.
