Friend asking for money back.

I met a guy online few years ago and we started talking and it became serious relationship. He said that he is 28 years old while I was 22 and that he is single. After a point, we thought of getting married too. I was staying away from home since my parents don’t support my education and then I ran out of money, so I used to take expenses from him totalling 1.5 lakhs. But I only took it because I thought we will get married and also he told me that I don’t need to pay it back. Or else I would never take such amount from anyone, I can’t afford to repay it. After 3 Years of relationship, I came to know that he is actually 37 and he has a wife and a daughter and when I confronted him, he said that he is divorced. Still age is a factor for me so I broke up and stopped talking. Now out of nowhere he messaged me randomly and when I told him that I am about to get married, he completely changed and he is saying that he has proof of bank transactions and that I need to repay him back or I should keep in touch with him. I can’t really repay now, my parents lost their business in COVID and I don’t have a job. Plus I can never repay such huge amount. Please suggest me what to do, I am currently in Hyderabad and he is in Mumbai and I took money from him when I was in Chennai.
