Boundaries are ideas we put into place to protect ourselves, and others, from being walked all over, or having our consent violated in some fashion. They are tools to create an environment where we aren't taking advantage of anyone, and they aren't taking advantage of us. In my professional life, in parenting, in public spaces, I have a plethora of boundaries. When it comes to my personal life, the relationships I share with people I love, it would be my ideal to have minimal boundaries, not because boundaries are bad, but because they wouldn't be needed.
I'm a pretty giving sort of person. I enjoy being in relationships where I can be generous to others, consider their needs and wants along with my own. If I find myself spending lots of time and energy holding boundaries in a relationship, that isn't being reciprocated. It's being sucked dry. It's settling for less that what I need in a given relationship to feel healthy and happy. It's putting up walls against intimacy over and over again to protect myself.
So, I'm working towards the radical ideal of reducing my boundaries by choosing to be in relationships and friendships only with those people who consider my happiness and health with their own. Because, sometimes the answer isn't to get better boundaries, it's to be connected with happy, healthy, considerate people who grok that the happiness of each individual lends itself to the joyous expression of the whole within poly, and chooses to think and feel in a more expanded context than self.
