Are expectations premeditated resentments?

I remember sitting in therapy a couple of years ago explaining that an ex had told me that "expectations were premeditated resentments". 
For a while, the therapist and I debated whether or not his outlook was a negative one, or perhaps if expectations were in fact, necessary.

This past week, I realised that most of my resentments have come from expecting the other party, the children, my partner, even my boss, to do certain things, provide in certain ways and then, in turn, fulfill my needs and my expectations - all of which revolve around me. 

I don't mean that I expect them to drop everything, yet I do, I have an unrealistic expectation that everyone is happy, everyone is on my side and everyone wants to pull their weight and add joy to my life. A cotton candy bubble of denial, that's me, the eternal optimist. Facts are, people are people. 

Sometimes for example, the ex fails to pay her part toward her children (that I'm paying for and currently raising) or she sets up the children for failure when she doesn't arrive with her family in tow as promised to their soccer matches - I simply get resentful. I expect a mother to be more than that. I expect her to be - me - to do what I would do, to move heaven and earth to be there, to ensure that my word is my bond. 

But when you learn to expect that the unexpected is going to occur, when you learn that your expectations may be unrealistic, aggressively optimistic or even completely off course, you're growing. Perhaps, like myself, you keep thinking that maybe this time will be different, expectations are often our greatest cause of pain and disappointment when we don't accept people for who they are and who they've proven to be. 

We expect from others, what we would do ourselves. Accepting that people will let you down, or at least fall short of your desires for the outcome in mind, is your greatest freedom. It's not that one shouldn't expect better from people, but it is necessary to free yourself from judgement of them when they fail to rise. 

So this week, I decided to see the circumstances in which I expect certain outcomes to prevail, exactly as they are. I expect that each time the children get home from school, there may not be a welcoming committee nor a parade of love showered from them to me. I don't take it personally anymore, it is expected. I have come to expect very little, perhaps expect humanness, routine and a little less pizzazz - then I can't be disappointed. They are after all, moody, complex and individual human beings. 

The same applies when their mother reacts with childish comments and hurtful accusations, I've learned to expect this, my expectations cannot cause resentment, because I know that she's incapable, or at least unwilling, to rise above the pain and anger she feels toward us and be a present and active parent. In the past, I had high hopes she would soften, change and reason with herself if not with us. 

A stone is a stone, and I shall no longer see the stone as a feather. So now, I let go and at the same time embrace expectations. They can be premeditated resentments or they can set you free. 

It's lighter and my life feels like my own again.
