Not allowed to socialise?

So basically I come from a Muslim family who can be strict at times but only when there’s logic with it. My friend who’s been friends with me for the last 2 years asked me to go out with her on Saturday for her bday and I said okay I’ll ask my mum. My mum doesn’t let me go to a lot of my friends houses only the ones she knows well so I said you can meet her parents but my mum is not letting me go. There are a couple of other friends going too. She says that there will be no supervision but we are going in a public place so there’s not a lot of danger and I tried to explain but my mum lashed out at me. How do I say to my friend I can’t come with her? She invited me last year too and I simply said I was busy but I think she got upset cause I always go with one or two of my other friends a lot and she thinks of me as one of my best friends too which she is but I really don’t want to ruin things I have just fitted in my new group which she is also in (we joined the friend group together) .... I don’t want to ruin things. Sorry for the rant ☹️

Has your friend met your mum? have you invited her round the house? Maybe if she saw her as responsible then she might be ok?

Are you planning on just a meal or what else? Any other adults going that could vouch / keep an eye on you?

Must be very difficult having such strict parents. It is quite unfair not only for your happiness but also your social development. Could her parents speak to your mum?

In any event invite your friend round and she can see being refused and its not from your want of trying?

I can’t invite her though because my parents don’t let me. Apparently my mum has had enough of friends and only 2 of them are allowed to come mine but she’s only other actual best friend apart from them my group are just friends it’s just her so I want to be a part of things so people know I have a social life ...
