Not surprised to hear your W's reaction to Retrouvaille. Probably looked at the info like you just handed her a pamphlet from the Hare Krishnas. I thought about that when I recently got a prayer devotions booklet with a lot of good articles on taking care of your marriage. Thought about showing it to my W and ask if she would read it, but then thought that she'd treat it like some unwelcome handout from a religious group.
They have to be ready for it. You can still try to sell Retro as a much cheaper alternative that supposedly has an 80% success rate.
In hindsight, I'm sure I should not have brought it up at this time. If she is going to MC for the right reasons, I know it took some courage for her to agree to go. I'm sure it seemed like I was pressuring her. Not my intention, of course. Just one of many mistakes on my part in this mess. I think I am making fewer though.
The info was still on the counter when I got home and I could tell she had looked through it. No more pressure. Just have to wait and see.
