Was that the boundary (jewelry and hoodie)? If so, you need to learn more about boundaries, okay?
First, we have boundaries for our protection, not to control others. Second, you do not ask her, you tell her. Third, a boundary is not an ultimatum or a request. Fourth, if the boundary is not honored by her, the response is your action. What will you do to protect your feelings when she openly disrespects you by wearing gifts from OM?
Be sure you understand something before you try to use it. Be prepared by knowing in advance what you will do. No action means the boundary was not effective. You have to follow through. So, what can you do if she continues to wear the gifts from her OM.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
