What can I do if ex cheated me financially?

I was in a relationship with a colleague since 2023 and trusted her deeply. Over time, she convinced me to take multiple loans totaling ₹4.5 lakh, citing family emergencies and making false promises of repayment. Despite repeated delays, emotional manipulation, and excuses, she misused the money—even after receiving ₹20 lakh from her father's retirement funds. Eventually, she cut off all communication. I am now emotionally broken, financially burdened, and paying EMIs alone. I cannot share this with my family due to fear of distress. I am seeking urgent guidance to manage this crisis.
