Whenever we get hurt by people around us, we protect ourselves by setting boundaries. An example would be having a friend who is critical of your happiness. Eventually, you learn to stop sharing your happiness with her - setting a boundary so that your friends criticism can't hurt you anymore.
However, these boundaries, should eventually be used as scaffolding. Let's say, for example, you have an ex who used to love to "borrow" money from you. Setting a boundary of not letting this person borrow money anymore is a GREAT STEP. But lets go a step BEYOND that. Now grow so far above the situation that the creep would never even THINK to borrow money from you.
Scaffolds, not boundaries.
