Exactly, Erebos, exactly.
My parents stayed together, but it has damaged me more than if they were to go separate ways. I've had to endure many years of anger and conflict between them (unfortunately much of it got targeted at me) and I sometimes just wish they could peacefully divorce and move on to healthier environments.
At other times they seem to genuinely love each other, but still they continue to fight on other occasions. My mother has accused my father of cheating on her. I believe she's wrong, and it's simply a case of jealousy and paranoia over some of my father's female friends. Based on his personality, I don't believe for one moment that he would engage in a second relationship in that way.
Many of my friends have experienced divorces early on, and it was hard for them at first, but they recovered and can look back on the situation without embarrassment or guilt.
If a relationship is irreconcilable, a divorce is a reasonable solution. Social taboos or religious opposition have no place in someone's personal life - romantic lifestyles heavily influence mental health of those involved. Children raised by conflicting parents may experience neglect and develop aggression later in life.
