Property related for divorce

I have two properties - (1) a villa (our current matrimonial home) which is in my name and built on a land I bought before marriage and construction during marriage and complete construction cost and furnishing was done by me. (2) an apartment in joint name/ownership (with wife) and wife as co-applicant in the loan (4 yrs of repayment still left). However all the EMI, down payment, Property tax, interiors cost etc was borne by me. She earns approx. 20L gross salary and my gross salary is approx 36L. Reading the discussions here, it looks obvious that she cannot have any right over the villa after divorce. What about the jointly co-owned apartment. Can she claim that and how to go about protecting it from her greed. The breakdown in marriage is because she has fear of intimacy and always denied me my conjugal rights and then other small trivial things spiralled and she was completely brainwashed by her sister into a postmodernist fundamentalist feminist thinking on every small things. She would hardly take any responsibility but always look for rights and entitlements.
