Hello Doctor, I Would Like To Discuss The Psychic Condition

Hello Doctor,
I would like to discuss the psychic condition of my wife who always thinks negative about me. I work in a multicultural company and I meet different people and I'm a jolly kind of person. I use to stay alone for so many years and tend to spend a lot of tym with my friends and like to make lot of new friends. And after I got married in 2015, I was very happy to add upon a new member to my life. But she started thinking negative and had a very negative perception about me. She thinks that I don't find her attractive and she starts comparing herself with my other friends. She thinks she is not intellectual enough to be my partner and feels inferior with me wen we are in a group of friends. So plzzz help me with this and kindly tell me how to get her out of this syndrome?
