Wow Spousal support?! Go for it! I'm sure plenty of LBS who were left in financial ruin will be rooting for you!!
Maybe I'm feeling jerkish today, but get a fat settlement, use it to buy a new car, get the better job, then go ahead and have the life she wants for yourself. If she ever asks thank her for showing you there is a better life than what you had and for showing you she was too selfish of a person to share it with.
Ok all silliness aside, your W is hardcore MLC, and you know what MLC's are not bad, as long as you don't forget those that have been with you all along. Tossing people aside is selfish, maybe it's time to consider at least beginning the road to moving on.
