this is harsh tbh u can collect ur evidence on diffrent occasions and once u r done with it report it to police and press chrges against her at the end whn a marriage bcmz this much suffocating should be left frgranted the fear of being deportd should not make u let go wats going on rise ur voice and if it costs u deportation its not a big deal . immgration works on protocols if u are in canada on spousal PR she cnt deport u at all do ur homewrk regrding collection of evidence and give her a surprise .
best of luck my God be with u nd hv his mercy on u ameen
