I agree with KatieKate - - your neighbor may be well intentioned, but dealing with such deep addiction as your wife is showing is not like pulling a wayward teenager back into the fold by tempting them with fun family activities. That would be like putting a band-aid on a gunshot wound.
You don't have to go there. The folks at Alanon and here do understand what you're going through, and we have your back.
I think KatieKate is right - all you can do is continue to do what you're doing and incubate your recovery as much as you can. As hard as it is, you are on the best path toward health for you and your children and that's what you've got to focus on, despite all the loss you feel from your AW's choices.
Come back here as often as you want,
