Congratulations on going to a Retrouvaille weekend! It is a big step, and I'm sure you won't regret it. How much is addressed about the lack of love and sex in the marriage? Nothing specifically is said about it. The presenters talk about their own marriages. Maybe those were issues in their marriages, and maybe not. So I can't say that they will talk about it.
You and your husband will discuss your own marriage in private, just between the two of you. Retrouvaille will teach you how to talk to each other. They will give you a framework for the discussions and ask questions that lead you to think about yourself, your husband, and your marriage. You won't be revealing anything about yourselves to the other people there. Unless you choose to, say in conversation at meals.
Don't worry about anything. Just pack your bag and go. They will take care of everything. And if things don't go well between you two, don't hesitate to ask one of the presenting couples for guidance.
