B is for Boundaries. Set boundaries, respect yourself. It doesn't mean you don't love, it is about caring for you.
Boundaries can be set in degrees, on size doesn't have to fit all. An outer boundary for the people in your life, an inside boundary for friends and some relations, and a closer boundary for close family and relationshiips, and they are adjustable.
You will find that some people ignore them, tramp all over them, step over them, and they have to be reinstated, reinforced, and made to stand up against abuse (mental, emotional, and physical), disrespect, and people who always get into your face and your business.
