Anna, I think if you can see yourself as the one who needs to maintain security and steadiness, that may help. You've acknowledged that your H is making half-baked plans from a place of infatuation just now. None of that is in the best interests of either your marriage or your family.
You seeking L advice is purely a means to maintain as much steadiness and security for everyone in the face of current uncertainties.
