I've never understood the mindset of women (or men) who pursue someone who is married. What can you possibly gain other than drama and heartache?
My uncle (I no longer refer to him as such tho) and aunt were married for 27 years. Once my cousins were grown and gone, he decides he no longer loves her, has an affair, causes much drama, and they divorce. He marries his "home wrecker", 2-3 years later pursues another woman, whom he later marries.
WTH? Isn't that what the latter years of life are all about? Once the nest is empty and your lives together become your own, all that you've worked and strived for, all that you've given each other, heartfully, doesn't it mean anything? Shouldn't this be a time of celebration, a time to re-acquaint yourselves with what drew you to this person in the first place? A time to enjoy the new generation (grandkids)? A time to enjoy the lesser responsibilities of not having to provide for a full sized family any more?
Idealistic, I know. Maybe this is why renewing vows is so popular these day.
