My girlfriend is threatening me

Me and my girlfriend were in relationship for 1 year and 7 months. In this time we had lots of moments and we had intercourse as well. My dad passed away recently and I moved to my home town. Due to some personal issues I took a loan with her and it’s an auto debit from her account and I’m paying it monthly. I’m Muslim and She’s Hindu, I spoke to my mom about our marriage where they are not ok. So I asked her did she spoke to her family and she said no. So I advised that we can break up mutually cause my mom’s mental health was not ok due demise of my father. Now she’s threatening that she will file a case against me and my family stating she can’t accept the break up and wanted sue my family. Before the break up I promised that I’ll repay the amount I took, and during the relationship itself she used to say that she’s not getting her periods and using the intimacy to be with her. Now she’s asking me to come and meet her cause she need to slap and scold me. Kindly me help on this please
