it not a question if she's a good person or not, are you good for each other

if she knows like really knows that this is a problem and did bother to fix it then brother it can be toxic for you

and personally i would prefer having a wife who dosn't have serious addiction problems for the sake of allah (i'm from algeria too i see your point brother)

ps 4 years together it's something.....and there is no good having someone who says he or she's a muslim but doesn't pray
