Later she took did theft in that house and my office friend asked her to leave. She earns 18000 per month and I earn 50000. She then agreed for MOU and the day she agreed, she was drinking and smoking. She also told me she is abusing drugs. I did advise to stop those out of concern. Next day she went to hospital and go admitted for low BP. She later sent me the bill of 25000 . I refused to pay and said that I will only pay that much amount after MOU has been signed.
