My ex gf says she's filing a case again of false promises of marriage

I met my ex gf through social media and on the first day of meeting itself we become physical (s*x), that to was initiated by her. She is 4 years older to me and a divorcee. Later after a week we met again got physical and next day she proposed me to be into a relation with her as her bf. We got into the relationship and had physical relation multiple times. I was jobless at that time. She use to spend her money on me even after repeatedly insisting not to do so because I was jobless ( I have text proofs). Out of sheer love I even told her indirectly on text that I will marry her. After 8 months I broke up with her due to some changes I saw in her nature. Also when we entered into relation she was not working. Now she has send me a legal notice that she will lodge a complaint of false promise of marriage and also demanded 10 lakh as compensation. ( Also I believe I don't have a rigid proof of get physical on our first meeting ). She has also send a letter to commissioner.
