Well.....that might help. But I agree with Bond, you have no standing to tell her who she can or cannot talk to. He's your husband; you should tell him. But the undercurrent stuff, the "he tells me I'm his everything" part, might eat away at her.
Anyway, back to Retrouvaille. If he wants to heal the marriage, move back home, and get back to regular life, then that's a good pathway to get there. So, whether he books it, or you book it, doesn't matter. You agree to go, one of you books it, you go, you do the Post sessions too. And by that time, everything should be a lot better. You will be talking about it all along the way.
And they will talk to him about not having a third party involved in the relationship before he can attend the weekend.
