What is a relational boundary?
A boundary is something that separates two things. Walls and fences are examples of material boundaries.
Relational boundaries separate people and help distinguish your unique identity from that of another person. This concept is relatively easy to understand when that person is an acquaintance or coworker. But it gets more complicated the closer you are to that person. It’s easy for the boundaries to become too loose or too rigid.
In contrast, it is not healthy for one or both parents to use the children as confidants for their marital problems or show romantic expressions of affection toward their children. These are boundary violations.
