If a vet's suggesting you might want to confront then I think you should consider that strongly. I can't remember what you said your green card situation was? If you think it might jeopardise that you might want to make a plan to wait until that's sorted out (can't remember how far in the future it was), or you know it will be sorted out, until confronting your wife.
