Kristin, also consider enforceability. E.g., "No texting AP around me" could be a good boundary, but you may find it difficult to enforce without seeing her screen. It may be easier to enforce "No excessive phone usage" or "No 30min+ bathroom breaks". I was proud a week ago when my partner was stuck in her own drama and I said, "My son and I are going out for some fun. Want to come, or need to take care of that?" She left. The boundary was not harsh nor mean, it was simply sanity and life preserving.
