Yeah, just to chime in on this part, if it were me, I would be giving you space, out of consideration. I have had several regulars message me about leaving over the years, and I always wanna support them in that, by not putting a temptation out there, so I try not to bother them too much.
I also know some people, use camsites when single, but then not when starting a new relationship, so I try to pretty much leave old regulars alone too, out of respect of not potentially causing trouble in any relationship they may be building. Different relationships being different, in what they consider being unfaithful and all, and I wanna support them in whatever they are doing for themselves, which brings them happiness. If it makes you feel any better, I had a regular for years who I absolutely adored, and I never messaged him once, after he stopped getting shows. I literally cried (privately) on and off for months missing him though, and not in a sexual way, just interacting with him, after shows via message and such, because I thought he was such a fucking cool dude. But I want to respect the fact he chose to leave, and I could never know for sure, what his reasons really were (he told me he was joining the seminary, which may or may not have been true, technically not my business at all though). He always paid fairly, but him leaving had no ultimate effect on my bottom line, however, it did and does still affect my emotions. I never once saw the guy, I only ever heard his voice, and got to know his personality.
So Idk but some models could have a similar thought process, and be trying not to bother you/ encroach upon your personal mental, social, and emotional space.
