Boundaries are funny things. Often invisible. They have to be set. Cannot always be seen. Vary from person to person.
Boundaries getting crossed?
Try this …
Set the boundary before it gets crossed. Not quick enough? Inform them they have crossed thee… line. Be direct. “Will you…?” Educate. “When you…then I…” Cite the consequences… “If you…then …”
Learn to say …”No.” Don’t explain, or justify your boundaries. It’s your life and your limits!
Effective boundaries, start with clarity.
Experience a lack of response to your limit setting? Restate, no response, then leave this is a relationship you don’t want.
