How do I (F18) tell my jehovah witness friend (F18) that im not interested in her religon?

So me and my friend have been friends since we were in grade 6 and we have always been close and tbh she's the most sweetest person I have EVER met. She's so kind and warm towards everyone and I love her so much.
However, recently I left my own religon (I was muslim) and told her that I don't identify as a muslim anymore. And ever since I told her that, she's been getting me into her own religon.
I remember once she invited me to attend one of her sunday morning meeting thingy (not sure what it's called) and it was online so I said yes, I thought it was just gonna be a one time special meeting so thats why I said yes. But apparently, this happens every week and she asked me to come again a few times and I made up some random excuses.
She always sends me websites about her religon and I just say thank you and that how Im busy currently.
Im always open to other religons and learning about them, but I literally just left islam and im kind of in a vulnerable state rn when it comes to religon, like, idk if i even want to truly leave islam, part of me is still confused about that...
And tbh, I don't really like her religon (im sorry if this offends anyone) its so strict. And one day she told me how one of the ladies in her religon goes thru her phone often and looks thru messages and photos, and how once she found some curse words that her friend sent her and so the lady took her phone away for a whole week!! who does that?!?! Its so wrong how she took her phone without her permssion, AND looked thru all her stuff AND TOOK IT AWAY FOR A WHOLE WEEK!!
So I told her one day that for now I just wanna be chill and relaxed and not worry about any religon right now because im not sure, and she was understanding of it but I could tell that she seemed a bit upset by it which makes me worried.
I just don't know if I did the right thing and I don't know how to politely explain to her that I don't want to be a Jehovah witness.
(TL;DR: Don't know how to polietly tell my jehovah witness friend that Im not interested in her religon without sounding mean)
