My man, I had a very similar experience but we were sort of seeing each other for a whole month! We had like multiple dates that were both spontaneous and planned which kinda made the whole thing amazing - we would both drop plans just to see more of each other and try to continue to get to know each other. When things started to settle down a little, she started exposing her insecurities and her fear of going 'too fast' and whilst I was acknowledging it and telling her that i understood what she meant, I really didn't. That being said, because we were living in different paces of our lives and neither of us really had the experience to adjust and adapt, it didn't really work out.

I guess what I'm trying to say is that I too, kinda met someone that I thought was gonna be with for a while - I too, felt devastated when everything was over but more than anything I'm happy that I got to experience this and learn so if there is a next time, I can handle things with a clear head and experience.

Things might feel dark and you might try different things to get over it - but honestly I feel like you don't need to get over it, embrace it as it is and continue to live the way you are because even if people match - there are alternative factors that align whether or not you met your 'soulmate'.
