How Can A Husband Wife Relationship Be Mended?

Hello Doctor, I am Senior Manager in India s top most software company.I have been married for last 2 yrs.During initial few months of our marriage,we both used to fight a lot.I was at that time in US.I had to incur some expenses on my wife s education.This really was very stressful for me.This continued for next few months.My wife really became very frustrated with me.But,since she was in US,there was nothing she could do to remediate the situation. Not that I dont love my wife but I just cant withstand spending so many dollars.According to her it was an investment but to me it looked like an expense. ITs been 2 years since then and situation has improved.We now also fight over money.She is a sweet woman but she always blames me for messing with her life.To me,I consider myself as a financiallhy insecure person who had lost his father in his childhood.I have deep hidden insecurities which I have tried to explain her but she empathises and loosed her cool once in a while.
