Re: Honesty is best policy
Why does your husband have to put the children in Islamic Sunday school? Why can’t you enroll them? Did your husband tell you that he didn’t want you to enroll them?
As for kids learning Punjabi/Urdu, if your husband doesn’t want to teach them, you can’t for him (obviously). Does your 10-year show any interest in learning the language?
I also find it surprising that after 15 YEARS, you have not learned some basic Punjabi/Urdu words where you can ask your MIL how she’s doing and stuff like that. Does your city not have a active Pakistani community? Your husband doesn’t have any other family members (sister, cousin, brother’s wife etc.) who speaks English and can help you learn basic Urdu/Pakistani? You haven’t been able to find a single online resource where you can teach yourself basic Punjabi/Urdu? Have you ever Googled this or looked up videos on YouTube?
