TP keeps in touch on dates, and usually has told me the where/when of her date; mind you usually once a week we have Mr. A over for dinner and hang out together, so the communication is much more free.
That being said I have not communicated with her at times on her dates strictly to give her and Mr. A their own space. Like this weekend they were having their anniversary dinner, and I intentionally did not message them after I texted Mr. A to wish him a happy anniversary and to remind him to compliment TP on her new haircut.
Polyamory is wrong! It's Multiamory or Polyphilia. Mixing Greek and Latin roots? That's wrong.
