Shutting it down

We have been exploring her having sex with other men for over 2 years. Read the books, had the talks and talks and more talks. Met some people in the lifestyle. She loves the attention but recently she said that she still doesn’t think she wants to go through with it. She thinks she only doing it for me. If this the case I want to respect her wishes. I’m just worried that if we no longer focused on this, my admiration will decrease and she might see this as punishment for not moving forward.
