After that we started regularly. We came to close each other later on and also established sexual relationship. She Assured me that we both will take care each other and always with you in life. I madly love her. During this period she took my all credit card and started some business and use the crefit card to repay self loan and use rest amount for personal use. Since i was in love with her i couldn't deny to give credit card. Later on she took personal Loan in my name and car loan also. Total amount is around 20- 25 lacs. She travelled many place in India with her husband and children during last one year and spent the money. Now she is not paying EMI for credit card and personal loan and stopped conversation.
