Hey Renee, I don't know what star sign you are, but it must be the hardnosed one. You are right though, fantasy (or any other) situations don't just happen. Positive relationships don't happen without effort. People have to work hard at them for them to work out to mutual advantage. Sh** happens, but good luck has to be carefully planned and managed.
What is required here is subtly - not a question out of the blue like 'Do you want to tell me all about your secret desire to wear femme shoes' and 'do you have more diverse desires to dress in femme gear and do makeup as well?' The guy probably has a long held secret that he isn't go let it all hang out on a nanosecond's notice.
My earlier suggestion was not fantasy, flight of fancy or sociological experiment. I've seen it happen and with positive outcome.
But hey, anyone can offer advice, but Lizbeth has to make the decision of how to handle her relationship.
