I have a friend who is friends with a mutual friend who is not that frum anymore, but is still respectful and all (like she wears a skirt when she’s at home)
But my friend told this girl that I still want to hang out with you and think you’re an amazing girl and all but when I am with you, you need to do x, y, and z. (I’m not exactly sure how she said it but you get the gist.)
Maybe you can do that, tell her I want to hang out with you and still be your friend but you can’t do x, y, z, when I’m with you.
