I am a 20 years old boy and my ex is the same age with me. We were together for about 8 months before breaking up. We were very happy together but we used to have issues before because i used to control her. We had a break up before but we got back together. After that we were happy only for a while. She started to message n talk with a guy for long hours. Both of us are 1st year undergraduates in medicine, while the other guy is a doctor doing his masters. She started to go out for dinner with this doctor often and then she started to go to his house alone and this things she hid from me. I got to know it from her friends and i saw her hanging out with him myself. She never tell me anything about this. When i confronted her, she said that they r just friends and i apologised for not trusting her. But then she started to refuse to meet me whenever i call her. She says that she is busy but then she will go out with this man. This man is rich and is working while i m not. 4 weeks later she called me up and said that she wants to end this relationship. She said that she is not happy with me and i don’t trust her and the doctor understands her better. I went through a miserable time because she broke up with me before my exams. After my exam i called her parents up and warned them about this doctor. I did not tell her parents anything about us. She hates me for calling up her parents.  All her friends hates this doctor. We feel like he is just using her for fun. She even fought with her friends when they advised her about this man.  I am studying in the same place like her and it hurts so much to look at her. I am scared that this man will play her off. I really love her and i don’t know where i went wrong. She is the first girl that i went so deep physically with. My friends advise me to forget her and move on, but i still want to make things right if i can. Do u think i have any chance???
