Relationships are hard work - there is no doubt about that. Negotiating boundaries is an important component in any relationship. Boundaries are flexible - we let people in as we build relationships with them. Boundaries are not walls though - walls keep people out.
Healthy boundaries are not a given - we are not taught them as children, and often they are learnt as we grow and develop and mature into adulthood. When someone throws a temper tantrum - or road rage perhaps. It is a sign that they have regressed and their boundaries have collapsed. It usually means someone else is hurt in the process.
Healthy boundaries allows us to have respectful, loving relationships. Boundaries may be physical, psychological and/or emotional.
This image speaks to a time in my personal life where I was negotiating the boundaries of a new relationship - needing to be respectful and caring - navigating the feeling space between myself and my new friend. Needing to be reflective, caring and empathic - taking care of myself in the process.
