We were in relationship since 2016 when we got admission in our PG course in reputed college.i was the only girl in my class, i had a year of experience of industry & he has industry experience of 5 years . we made our whats app group and our number get exchanged ,he started massaging me , and within 3 months he is saying that he likes me a lot, so i told him don't play a game. I took it into joke. bu he started following me and asking me about a coffee, he started massaging me that how compatible we r, how many similarities we have. He started meeting my friends too asking her to tell me that how he is best for me. he was so serious then i told him i don’t want to be in false any relationship i want to be marry. he was a Brahman & i am of other caste also he is from rich family & i am from simple middle class family. i tell him to ask his family first and then i will think. I never said yes until he said my family has no issue i asked them & they are highly educated. His mom is judge & father is IIT pass out. Then also i didn’t say yes then he hack my app i don’t know how & massaged me that why r u saying no to me. the we were selected for the internship in same company we used to go together to the company. Then feel he is genuine so I said yes to him after 7 months. He was too so caring and we used to go to the different places together we were so happy. After that he started telling me how good it feels when we touch each other hug each other. One day we have kissed. and after that he took me to his house when nobody is there. I never allowed him to do sex but we used to have oral sex at his house. But every time I ask he is going to marry me or not & he said yes. but when I ask him to get married he started giving me excuses like family is not ready. I am adopted parents has cancer. I trusted him every time .one day he post his engagement pic I was shocked I called him he said I don’t care now .i met his mom after that she said he never ask home and delete massages & move on . I met that girl. Her mom met me & told me to move on. They all humiliated by asking so many questions his family humiliated me. I was depressed I tried to kill myself I massaged them that. They file a complaint against me in women commission, they told me and took my sign on a paper of matter that I will not massage him in future.
