Assalam-o-alikum Brother Mohammad Jamal,
Ramazan Mubarak and Welcome back to TTI.
Brother you converted to Islam last year, nearly a year ago, but your situation with your wife has remained the same.
I know you love your wife and you worry about her and your children. I understand this... I would be worried too. But the solution to this problem is not to continue to stay Muslim inside and continue to "help" wife and children to go to temples etc where they worship false gods... Instead I would have implemented some strategy to achieve my goals.
Kolkata has a huge Muslim population. So if I was you then in this period I would have befriended with several Muslim families, their female members would be friends of my wife, and I have atleast introduced Islam to my wife and would have given her several books or litrature to read so that we could atleast talk. I would have used this bargaining chip that "Hey I will openly announce my conversion to Islam to everybody if you do not start reading Islamic books specially Quran".
Brother can you list what you have done in this last one year period to convince your wife to learn about Islam ?
If you are worried that she will leave you if she finds out that you converted to Islam, then isn't this a shame that she could leave you for a false religion but you cannot even talk to her about the true religion which you believe is correct and will lead you to salvation in the hereafter.
Brother if your wife & children die as Jain/Hindu then on the Day of Judgment the same wife & chilren will be blaming you that you had the truth with you but you didn't share it with them, and now they have to face this terrible punishment. What will you do then?
So you need to have a plan and a strategy to resolve this problem.
We on the internet can do only so much, the rest is up to you. My Duas are with you that Allah (SWT) protect you and guide you and help you in achieving these goals. Ameen !
Wassalam.
