Often, our accusations are justified. We probably are feeling hurt and frustrated. In those moments, we may begin to believe that the solution to our pain and frustration is getting the other person to do what we want, or having the outcome we desire. But these self-defeating illusions put the power and control of our life in other people's hands. We call this codependency.
The solution to our pain and frustration, however valid is to acknowledge our own feelings. We feel the anger, the grief; then we let go of the feelings and find peace - within ourselves. We know our happiness isn't controlled by another person, even though we may have convinced ourselves it is. We call this acceptance.
Then we decide that although we'd like our situation to be different, maybe our life is happening this way for a reason.
