Maybe I am jealousy but I am really uncomfortable with his broth

 My mother-in-law is the decision maker so he treats my mother-in-law like a queen, while he basically does not care about my father-in-law at all now. He forgot that my father-in-law traferred his summer property to him 25 years ago and now the property worths several millions. He is still unsatuated with what he gets so far.
