Sun&Moon, thank you for your opinions on the matter. We have mulled over the possiblity, with new information that has come to light to us, that the couple (Bill and Ann)each had the following in their backstory:
*Bill had been married before for 11 years, and he and his previous wife were in the LS. They divorced two years ago.
* Ann has been a unicorn for a couple for 4 years ago, for a period of about 2 years. she then took a break from the LS to try and go vanilla for a bit.
*Ann while she was a unicorn, was a sub to the husband who was her Master.
*Bill and Ann have only been together about 6 months, they are not married, but are in fact GF and Boyfriend.
With this new info we gathered from asking around, we realize that their issue maybe that being in a new relationship, may be their whole cause of why Ann was unresponsive / talkative to me in our chats. As you said "maybe she doesn't want to get too heated in the group chat so her own husband doesn't worry," in a new relationship with someone, I can see that being the possibility.
We continue our search and continue to grow and love as a couple. Thanks to all for the responses.
