I have only ever had one break up that went well. It was one of those "I have no feelings for you". I was the one ending it too. We both agreed it wasn't working and it just ended. We talk here and then, but not often.
As for every other relationship to end, I have been a complete mess and at times, made things worse. Where I could have salvaged a friendship, I have completely destroyed everything. It's not my most proud of times.
I think every break up is as different as the relationship it is for though. I have no experience of a poly break up though and hope I don't have to. But I suppose it is bound to happen one day.
