Leaving work because of intermingling

Q: I am a tuition teacher of 22 years old. I also maintain purdah. 7 months back I left a tuition because of intermingling. I told them about segragation and I told them to separate my room. They did but maybe they were not happy with me. My conversation was not so much with the male members of the family but I left just for the sake of purdah. They said to me that I cannot do anything in life with this purdah. With a heavy heart I left the tuition. Now I am teaching in my home totaly separate. Am I doing the right thing?
