<human>: Backstory: We started dating our junior year of high school (3 and a half years ago). She was great. Probably the best hs girl friend I could ask for besides being a tad clingy (she felt the constant need to be texting/calling each other). We had a really close group of friends and everything seemed perfect... until  we went away to college. We decided it would be best to not go to the same school but still stay together. It was tough not to be able to see each other but it wasn't terrible. Although it seemed like it was going ok, I always had the feeling in the back of my head that I was holding myself back from the "college" experience. 
           Fast forward to summer after freshman year and I decide to end it. It was one of the hardest things I have ever done but I felt like I was doing the right thing. I  had this plan in my head that was going to go out and meet a bunch of girls and hook up with someone new each weekend like I saw my friends doing freshman year. This plan worked for a while but those one night flings felt so unfulfilling compared to what my ex and I had. I feel like I thew away my best friend. So I guess my question is should I give it more time (its been almost a year since we broke up) or admit I was wrong and go back to her? I would appreciate any and all advise.

Can you summarize the given text in a few sentences?
<bot>: Broke up with hs girl friend during college to get the "college" experience but I now after almost a year, think that I made a mistake and should go back to her.
