Congrats on the sweet consulting gig! What a GORGEOUS time of the year to be up in Maine! I hope you truly enjoy it, and use the time to recharge your emotional batteries.
Your wife is going to likely pursue you during your time away. My advice would be to stay dim (not dark), and to keep it about the kids. If she tries to start R texts, e-mails or phone calls, I would advise a "We can talk about this when I'm back. Right now I'm trying to focus on the job assignment, and getting to know 2thepoint again, and figure out what he wants out of the rest of his life." (or something similar).
