it’s a possibility … but nothing that i can guarantee a 100%. i dont know her or her reasons. it could be just about your hijab, it could not be about your hijab … goes both ways .. it could be about your suffocating views, it could not be about your suffocating views (i.e. if they are suffocating to begin with) .. it’s an imagination of what you’re like upon which your niece is resting her opinion. she has nothing concrete to base it on.
does she know other people besides you who live in the UK? does she know the family jin say rshta aya hai? are they also imaginatively similar to you in her mind?
but i’d agree with as someone said above … that go there not to specifically sit and explain to her how you feel everyday that you’re there … instead … let her observe you while you live your life and have a nice holiday … and if need be … towards the end you can have a conversation if she still feels the same way about you …
