<human>: Give me the gist of the text in a nutshell

Hey everyone, as you can see from my post history this was sort of a long time coming. We had been together since our freshman year in college and were both each other's first everything. There is still a lot of love between us and we had talked at length about our lives together and our kids etc etc. Unfortunately our careers took us to different cities and this took a toll on our relationship. We've gone no contact of course for the near term with the understanding that at some point we want to be friends. 

I guess what I am looking for is tips from you all about how to stop feeling  like I've lost something. The end of the relationship honestly feels like someone close to me has died. Even talking on the phone last night where we both agreed we wouldn't trade the past five years for the world, it seemed to be that good bye didn't do it justice. 

I understand fully why this needs to happen but I still have this nagging feeling like she was the one for me and like I was cheated out of the life we had planned together. 

Also the regular fears about how we were so very similar and got along so well yet we still couldn't make it work. 

I have lots of great friends and hobbies in my current city (trying  to get my pilots license!) and a job that I am relatively happy with, but just looking for advice or similar experiences that you have.
<bot>: First everything gf and I break up very amicably after five years still with a lot of love for each other, looking for tips +advice.
