I am absolutely thrilled that you have found your RT One! You are a special person who deserves that level of submissiveness and joy to complete you!
However, I do not understand your decision to leave MTC. My next statements may anger you, but friendship sometimes involves making honest statements that your friend may not want to hear. If I were 100% satisfied with my RT situation, I still wouldn't leave Gor. I have a need for hobbies, relaxation -- hell, simply sharing my day with my Gorean friends and expressing myself through role-play. I don't see why it has to be a choice between Him and all of us. Your decision, to me, seems unhealthy. In my opinion, life and love shouldn't be about giving up a whole set of people for a lover/owner. Many RT owners allow their submissives to chat in Gor or BDSM -- or even VampieLand or Medeival -- because they recognize that submissives still need those friendships and creative outlets.
Even if you were around much, much less -- once or twice a month, like I am -- you could still be around. No one here would call you a bad slave just because you couldn't be in your online home 6 nights out of 7. We have military men who make it to camp about five times a year. We still love and welcome them. We have people with severe illnesses who are in camp for a few days at a time and then not at all for months at a time. We still look forward to their return. Hell, you don't even have to take a LOA, let alone shelve your character. You could simply announce that you won't be around much and leave it at that, and no one would think any less of you.
I hope that you will not feel that I am trying to judge you or look down upon you, because I am not. I also respect the fact that your life decisions are your own. But, again, I have to be honest... Simply put, when I read your post, I thought to myself, "She's found a RT Master, awesome. So? How does that have anything to do with Gor, and why does she need to leave MTC?"
I just don't see why one aspect of your life has to totally exclude the other.
