IMHO... NO ONE ever has any right to tell me:
1) Who I can marry. Regardless of race, gender, age (beyond the age of consent, of course) or any other determining factor, its my business.
2) That I MUST marry. If I decide to enter into a "domestic partnership", "live together", or just plain "shack up", its my business.
BUT MOST OF ALL
3) That once I have entered into a relationship, I have to stay there.
It always floors me how society in general thinks it's any of anyone else's business what happens within MY marriage/relationships. Regardless of the reason - infidelity, abuse, or just plain old we-have-grown-apart-and-I don't-love-you-anymore - NO ONE should ever be forced to stay in a marriage they don't want to be in.
Divorce is hard. Hard to get, hard to get through, and hard to deal with afterwards. But if I have made the decision that I want to dissolve my marriage and deal with the consequences, then it is absolutely no one else's business, and no one has the right to judge. I love Jennasis's "grass" analogy - maybe the grass IS greener, maybe it isn't, but if your grass is totally wasted, burned out, gone, ANY grass will be better. And maybe you don't want any grass at all! Personal choice, no one else's business.
And yes, I have never been divorced. Never even considered it. Married 17 years this summer, very happy. My DH was married once before me; horrible, imploding, mess of a failed 9-month marriage. I witnessed that one, it was ugly. My mom was married and divorced twice by the time I was 8. She taught me three very important things: If everyone else says he is a bum, he probably is a bum, you just aren't looking at things clearly, and Stand up for yourself, no matter what anyone says, your life - your choice, and There are far far worse things than being divorced and alone. If anything ever changed in our relationship; if he cheated, or was abusive, if the trust and respect and love were to be gone, I would walk away, in a heartbeat. It would break my heart, but I have too much self-respect to stay in a bad situation.
