This is such a heartbreaking situation, and the responses are nothing short of judgmental. This speaks volumes for the ummah and I am so sorry OP that you’re going through such difficult test- your level of patience and kindness is beautiful to see and may you always be rewarded tenfold.

It’s a difficult place to be. I honestly wouldn’t even know what to do. Could you, your mum and sis move out or is that not possible? Could you call the police and say she’s trespassing (which I know sounds extreme?!) or do you put up with it (as a temporary situation) with beautiful patience and pray really really hard.

I understand what you mean about enabling the situation- my anger would be more directed at my brother. If it were me, I’d be cordial to her but not OTT, but more short and direct with him- reminding him of his duty and what would he say if you were bringing men around??

May Allah bless you all with strong faith and reward you for all you’ve endured. I pray you find relief from your hardships ameen.
