Money taken as friendship and now threatening me

Dear Sir I would like to tell u full incident : a) Mr Ganesh is our family friend as friend ship he asked my 1.5L during Jan-2019 for personal family expnenses same will be paid within 6 to 8 months with interest of Rs.3 per Lac. So I agreed and paid him 1L during 10-Jan-2019 thru NEFT from my ICICI bank to His ICICI Bank account. During Nov-2019, I was admitted to hospital for cardiac arrest and requested him thru phone & personal contact to return my money with interest but till date only he is extending the date no commitment of returning. During Apr-22 to Jun-22 He again told me due to family issue pls help me 10L , I am selling my house I will refund u full amount with Interest by Dec-22. He was continuously following up so I have paid him in cash and some amount to other from were he has taken a loan. So total I have paid him 9.5L till Jun-22. (So as on 31-03-23 total amount I should get from him is Rs. (4000x9x8.5+3000x51)= 4.59+9.5= 14.09L And now he is threatening me if u tell any body of 8.5L I will clearly deny I have not taken from u I am only responsible for 1L only. So please wait I will return you But he has sold his house and got full settlement of 1.30Cr but still he is not paying me pls look into. He is playing with my honesty because I have not taken any signature for loan amount because he was my family friend, and now he is cheating me. Pls look into and advise me.
