1. Fully concentrate on the business venture -raise funds from other sources. Absolutely dont tell dev or anyone in the dixit house about this. They dont need to know as they thought sona didnt have to know riyas rishta - i dont find any moral issue
2. Go to work before dev wakes up and come really late.. Dont justify ur working hours to anyone
3. Show how a bahu behaves when she is treated like outsider- dont go wedding shopping , dont show any interest in any activities at home
4. When you have time off go and spend time in bose house - dont tell anyone where you are going
5. Dont take any insults lying down give intelligent replies. Show everyone their worth.
6. If ishwari asks u to come home early - dont go
Just disregard all ishwari and devs requests
Make your stand very obvious - if they treat u as outsider then that is what they r going to get
7. If still there is no change in dev just walk out
