Hello, I got married 15days ago and my in laws hided that there son is having a skin disease which do not have permanent cure i have consulted many doctors for clarification and they that this disease may occur again in future and now the disease will not cure for 100%. I got to know this very next day after my wedding and i am shocked by seeing his disease that is all over the body i cant see and digest when i ask them about this they are telling me that we thought that this will sorted but now it is not and we thought of sharing this with it earlier but dont know how you will react that is the reason we did not informed earlier this is the reason they said and i am feeling it as they cheated on this and dont know how to proceed further on this. Kindly suggest me what to do. Mainly my parents are not supporting me on this they are asking me to adjust on this my intention is when i dont have any issues in me then why should i accept my life the way it is now. I deserve better than this i dont want to compromise and adjust with these people. thank you.
