Mudshark1. What are you waiting for? You obviously don't have a marriage. It's time to split.

As the counsellors say, let's list the pros and cons. You are extremely affectionate, earn decent buckaroos, would die for the right woman and you're good looking. She, on the other hand couldn't care less, hasn't got a clue, didn't command respect from her unbearable children (and you a teacher too) and is having an early menopause.

You should obviously just leave. There is no need to feel guilty about the children. After all they are not yours. But you say you hate being alone and walking out alone is a bit like jumping off a cliff (I know). Perhaps it would be better to take a leaf out of Guest Guest's book and start an affair. A man with your attributes shouldn't have a problem. Get a younger woman who won't hit the menopause until about the time you start having trouble with your prostate, then she'll be able to sympathise with you. When the affair's well established you can just tell your wife and leave immediately.

Or you could try being totally honest about your feelings and listen to her point of view. Then you will be able to make the most amicable arrangements possible.
