but I'd get most of the life I am familiar with back.
Honestly, was the "familiar" life all that? The familiar life let to your wife cheating on you. To me this sounds like people wanting what they can't have. I can tell you that it's more difficult the second time around. You will be more wary of her and she'll be more inclined to leave if things go back to what she hated before. It isn't all sunny and nice the second time around. The trust will be really hard to restore. I would be very cautious about trying again.
