<human>: im just looking for some advice on how to get past this, i ruined the best thing to ever happen to me in one night when i was drunk. I lost myself for a little bit and just want to know how i can move on. I have never been in love before her, never felt heartbreak, i know i learned way more then i wanted to learn that night, and my next gf will be the luckiest girl in the world because i dont want to go through this pain ever again. this happened almost 3 weeks ago and i have just been a mess ever since. I know what showed that night will never show its face ever again, i just feel like i will never get past this. I guess i am looking for people who have cheated on someone they love in the past and how they moved on from it.

Can you condense the text into three sentences or less?
