An Expectation Free Zone

I've come to accept that I am 100 percent responsible for my own happiness. I've come to accept, after a fairly long process, that to expect too much from others is unrealistic. Perhaps unfair, even. I've kind of even taken a zero expectation approach, because this at least removes the pressure from everyone else. You are not responsible for my happiness, my hopes, my psychological wellbeing. You are not responsible for my dreams, my ideals, my crazy tangents. You're off the hook. You're free. You owe me nothing. I wonder whether we sometimes lay excessive expectation at the feet of others, placing them in an impossible position? Perhaps we just expect too much from others in general? And when they "Let us down", we expose them to feelings of guilt and low self esteem? I wonder whether the kinder thing, the more realistic thing is simply to free others from all that? Its an open and unresolved question for me. The obvious risk is that we insulate ourselves from meaningful connections, perhaps shutting ourselves off from potential experiences that could make our lives richer? I can't honestly work out whether my perspective is born of cynicism or just the plain acceptance of the way the world is? I know that I do not want to guilt anybody into anything, or demand that they become something they are not. Perhaps there is no one answer? Could it be that much depends on the other person/person's within the equation?
Ultimately, I get to own my own experiences. I don't get to project my feelings. I'm responsible for dealing with my own issues. I'd be really interested in getting the thoughts of others on this. The waters muddy with me right now. I can't see so clearly.
