In case you needed official permission, you actually aren't required to share your relationship (or other) decisions, even if it directly impacts a person you care about. Sometimes, it can even get in the way of the effectiveness of your objective. Telling someone you are going to pull back from the relationship may or may not have the intended effect you are after. Asking yourself, "what is my intention [or intentions]," is one of the best questions to help determine whether you can ACTUALLY bring about the result you are after...you may even discover hidden intentions in yourself that you realize you need to let go of because they don't match your values. Better to find out than to operate on auto-pilot!
