There's no doubt I made a number of errors during the course of my recent relationship. I think if I handled everything properly from the beginning, we would have either broken up much sooner or remained together. I think we were incompatible in many essential ways, but I can't know that for sure now.
In hindsight, I know what I should have done, but I can't undo what has been done. All I can do now is use this episode for future reference.
