<human>: Hey guys, it's the first first evening in 6 years that I am truthfully alone and I'm devastated. 

My fiance and I were together for 5 years and had without a doubt one of the most beautiful and closest relationships I have ever heard about. But it all ended last night. The details are too difficult for me to put into words. But for the first time in 6 and a half years I feel completely abandoned, heartbroken and just torn.

Today was the first day I haven't had any contact to her and I'm feeling completely empty going into the night.

I have no one to really turn to as we were living together and I don't know how to just go back to my old folks. I don't want them to think any different about her, or think she's a bad person.

I guess what I'm getting to is that I would love some advice and or someone to talk to.

Can you condense the text into a few key points?
<bot>: had an amazing thing going, fiance of 5 years decided that she wanted to go behind my back and see other people. Need help.
