How you are - your very being - will trigger certain people. That does not mean you should shrink yourself, in the unattainable hope to avoid ever triggering someone else. Instead, when a trigger happens, you can use it as a doorway for connection.  Lean into the doorway, holding compassion for yourself and the other person. This is where the real magic happens. There are certain wounds each of us carries that were created in relationship with other people. Repairing these wounds fully,  requires healing in relationship with other people - coupled with experience, time, and space for a new pattern to emerge.
