Stuck in a Troubled Marriage for 14 Years with 4 Young Children - What Should I Do?

I m married for last 10 years but i had a troubled marriage after 6 month of marriage. My wife behavior is very bad and aggressive. I tried to save marriage due to my children but it is impacting his mental status. I want to move on kindly suggest

I have second marriage and staying 9 years. Now my age is 50 years, and my wife age is 40. I have one child years of years 6. I am in a managerial Position in a company. My wife is a Housewife and her behavior's, misconduct, lack of ownership towards me as well as home is always upset and irritate me. My child was born by IFV method due to her irregular period. She has got many opportunities to recover this problem and treatment also got an early-stage life. Due to lack of her understanding and knowledge, lack of own effort, irresponsible and liar nature, did not overcome her problem and therefore, we cannot go for second baby. Now me and my son also suffer from 2nd baby, though I have sufficient resource to look two children. I need to monitor all the things of my son’s health, extracurricular activity, education etc. She also neglects my mother. I feel she is very quality less and very dirty woman and talking valueless, not concern with health of own as well as other family member. Therefore, I and my wife staying in same home, but from last 4 years I have been separated from my wife and living in separate room. Sometimes I think to separate from my wife, but it may affect relation with my son as well as his mental condition. I am trying to adopt a second child also. I found she is not concern with quality, health, and economy. Therefore, I need to do home marketing, finance, monitoring home, health etc. which has already affected at my career also. Please advise me what to do? I feel my future is very dark with my wife. No emotions, no love and intimacy in the relation. I do regular walking & jogging and gardening is also my hobby.
