Divorce battles where children are involved are the worst. Don't believe the myths that children just bounce back and it hardly affects them. I've read too many studies that suggest otherwise. It's even worse if one of the parents then marries into a ready-made family and the child of the original marriage has to try to fit into the new family dynamic.
Having a parent removed from your household at a young age for any reason is traumatic as all hell. Unless your spouse is actively abusing you, unless you want to damage your kids for life, stay together, you selfish breeders. You think you can't stand another minute with your annoying spouse? How about your poor young kids who can't yet articulate the terror and pain they are going through? You're sacrificing them up on the altar of your personal comfort.
There's nothing like being a child, witnessing a tremendous custody battle for you, and feeling like a token in a vicious game. Mother wins, and then every time you visit Daddy, you get to be asked "So what is your mom spending the child support money on?" You get to find out exactly how much you are worth to Daddy (in my case, $300), and you get to find out just how bad Mommy is at managing the finances. It's a laugh a minute, I tell you.
I know, anecdotes prove nothing. But man, I just want to rage at every person out there with kids who gets a divorce for "incompatibility reasons" before the child is old enough to be semi-independent.
