I agree with Daisygirld regarding sex and Ayn Rand's quote, thank you for that!

Regarding reasons not to remarry, I would like to add:

1. Drive your own sports car and not share it!
2. Shop all you want!
3. Sleep in on weekends!
4. Pursue your dreams!
5. Take the trip he never entertained!
6. Take as long shower/bath as you like!
7. Don't have to listen to his snoring (well, my dog snores!)
8. Be ambivalent!
