KG - Examples (keep in mind, I'm not saying these are the specific boundaries you should set, that is up to you):
1. "If you are communicating with AP while we are together, I will leave."
- She starts texting AP. - Boundary: You leave.
2. "I will no longer tolerate you coming to my house drunk in the middle of the night with no warning. Next time this happens I will ask you to leave."
- She comes over drunk in the middle of the night. - Boundary: You ask her to leave.
Boundaries involve consequences. Many of us fall into the trap of saying "I won't take you doing XYZ anymore" and then when XYZ happens, we do nothing (which shows there was actually no boundary).
