Letting go of expectations is incredibly hard. I'm trying to see when my expectations are coming from my own issues or when are they simply just something that the situation calls for. For instance, I have been looking back to some times in the past when H let me down. Recently, I had the major realization that a year ago, I wanted H and I to move on in our lives. H clearly was not in a position to do so but I kept pushing anyway. I would send him job listing after job listing. He applied for a position in a location where I wanted us to move. H wrote the most disturbing cover letter I have ever read. It started to dawn on me that H was not doing well mentally but instead of addressing that, I was more disappointed that he had ruined his chances of ever working at that company.
So, my point is we don't need to eliminate all of our expectations but rather examine where they are coming from and what they would supply us with if they were fulfilled or what we would think that we would lose if they were not. It's much, much easier to do this AFTER the event has occured.
