So how did this go? Original post was almost a month ag...has it happened or still being considered?
If still being considered, I say let her go. It will be a fantastic time for both of you. MY wife has traveled for business with all of the guys she has had relationships with, sometimes for as long as a month (Boss/Lover and her used to spend a month at the corporate condo doing business planning and they pretty much lived as wife/husband when they did). Other guys were 2-3 day trips, sometimes extended to a week for "business". It gives them time to REALLY ger involved sexually, get to knw one another much closer, and the sex is FANTASTIC when this happens.
Update us as to how it went (or goes). CW
