Why is there permanent alimony and how common is it?

I know a guy who is a surgeon and he has been divorced for 20 years but still pays alimony and constantly has his ex texting and calling and demanding for additional money on top of the alimony... like she was demanding him send her 30,000 and she has a doctorate degree and won't get a job. The marriage ended because she cheated on him and left him. How is this a law? I understand paying alimony a few years to help the other get back on their feet but permanent alimony?
