Maintaining purdah when keeping family ties

What is more important: segregation between men and women or keeping family ties?

I am asking because in my native place and family, people have almost completely left the rules of segregation between men and women. So, I'm afraid to visit my family members. I have been concerned about the rules of segregation that I stopped visiting my relatives for a long time. But because of this my relations with family members became really bad, which is another bad thing in Deen.

Also, in my current situation I can't survive alone. I need help from my family to survive. I cannot stop visiting them.

Also, many of them are not able to understand my stance on this issue. Many of them are getting a bad image of Islam when I give less importance to family relations. They seem to be going further away from Deen and Imaan because of me.

So, how should I balance?

I am a weak hearted person. I may not be able to boldly oppose the malpractices when I visit my family. Also, I can't bear to see their hearts broken because of me. I am also not able to convince them of our rules.

Now, I am feeling that I should give more importance to maintaing family ties. I am feeling that I should visit them even if I may unintentionally do some sin in the process. Is this the right way to proceed?
