Yes they used to meet up as friends, talk about the usual, relationship issues and such then they came to this sex agreement. It is therefore unfair of me to ask her to stop replying if he contacts, or contacting him. Apparently it's not even every week. It's something I need to realise exists and get over it. I do worry that if we argue she may take comfort in him but that may well be all in my mind. She says she values trust and truthfulness over all else
