My husband is 40 years old and he is getting some very abnormal feelings from past 2-3 months, he says he is hearing people talking about him when there is nobody around him, he doubts that i am using some communication to threaten him, he doubts me that i doing some conspiracy against him, if he goes to public places he says that people are coming to beat him up in groups which is not true, because i was with in some situations where nothing like that was happening, but he was telling that people are trying to attack him . Please advice what is this problem and how i should cope with this
