Permanent alimony is VERY rare. Now MAYBE if she was pushing 55, had never worked a day in her life, then she might get permanent. But even then, it's a crapshoot. Alimony is usually only temporary as there are no reasons a person can't get back to work and become self-supporting after a time, unless because of advanced age.
Aside from that, I'm gonna echo what the others have said. My first thought was a troll post designed to stir up a flamewar. Maybe, or maybe just someone who is very naive and thinks they can pull one over on someone. Why in the hell did she marry if she didn't believe in the vows she took?
