I am not sure what's typical in regards to the WAH bringing the o.w. around to meet family and friends. In my own case, I know my H. brought o.w. to meet his brother 4 mo. after they met, and as far as I know that is the only family member she ever met. I do not know if he brought her to meet any of his friends. I am going to venture a guess and say that I think they go one of two ways with this: Either they keep the o.w. away from their "real" life (meaning their family members and closer friends) because something is telling them they are not to mix the two situations or They jump right off the deep end, believing far too quickly that they are "in love" and they rush to introduce the o.w. to their new family in hopes of pushing this "new life" into play. I think the ones that do the latter make the bigger mistake, and they probably have the least chance of having a real relationship with the o.w. in that case. Just my two cents.
Most of us really marry only once. First love endures, even unto our dying day. And we never really divorce.
