Wife asking me to quit my job to relocate to her homtown

I am working in an R&D Lab in Bangalore for last five months. The job profile is good. Before that, I was pursuing my Ph.D. So, this I am married to a girl from my hometown Kolkata. 5 months ago my wife relocated with me to Bangalore. She is an M.Sc, B.Ed. When she relocated, she was unemployed. In Bangalore, she applied to some schools and got offers also. But, she is reluctant to join in any of theme bcoz she needs to wear sari which she is not habituated to. Now, she is forcing me to quit my job and go to Kolkata to find another one even if it is not so good as compared to the present one. I keep on telling her that I cannot do that as leaving such a job at this time of my career will have long-term financial implications for both of us. I belong to a financially weak family. So, compromising with my job will only lead me to financial as well as emotional agony. I help my wife in every manner in almost all household chores. However, she is now hardly doing any kind of stuff like cooking for us. Most of the time she either sleeps or harasses me emotionally like crying, threating to commit suicide, nagging etc. I feel totally exhausted emotionally. All this affecting me psychologically and I am not able to concentrate on my job properly. I need immediate help to get out of this mental agony.
