Mentally harassed by father to marry

I am 38 year old well-educated woman and single. My father is constantly pressurizing me to marry against my wishes as I am not at all interested in marriage. Because of my age, he is unable to find a guy of my age in my caste as he doesn’t want to look for guys in other castes due to which there is but obvious very limited choices and below average quality available. He simple says i will not for boys in other castes and if you can then do yourself which a tad bit late now with me not interested in settling down at all. He has gone to an extent of telling lies to prospective grooms’ families that I am much younger in age (like almost 10 yrs young) simply to get rid of me. All this is further making me infuriated as I don’t believe in starting any relationship, especially a marriage, on the foundation of lies. Moreover, I am old enough where he cannot pester me to do anything against my wishes. The problem is that my mother becomes instant victim due to this nasty father-daughter altercation and I am worried that she might have to face more brunt coz of this. What help can I get legally in order to stop this constant mental torture which my father is always inflicting upon me in the name of society? I am not even dependent on him financially...although, I am sure he won’t even give me a penny if I ever need any financial aid. How do i deal with this monster, unfortunately who is my father, so that he stops bullying me? The issue is in India, automatically a single woman after a certain age is considered as an evil and when she asks for help, even the legal system be it police (if I go for an FIR) looks down on her. Please help as it is making me mad to the extent that I might take an adverse step with no point of return!
