Any chance for spousal support after remarriage?

I'm remarrying less than a year since getting divorced.  New husband makes much less than ex, who I was married to for over 18 years.  All those years I worked for/with him, but no salary, then was a mom, and now I'm at a serious disadvantage in income earning potential.  My attorney says that because I'm getting remarried, ex doesn't owe me any kind of spousal support ever, period, once I say "I do."  Doesn't seem fair to me.  I just want to start a new life, but dang it, my ex was able to make a real good living because I worked for him for free for most of twenty years.  Not sure whether to believe my attorney or not.  We're in California, btw.  Thanks for any insights.
