This girl thinks she’s gonna be my bridesmaid..

So I’ve only known this girl for a little amount of time and I feel like she’s trying to get really close with me so she’s invited to the wedding. She brought up how she’s gonna be in/at my wedding but I’m not completely comfortable with her like that yet- especially to be a bridesmaid when I’m only inviting immediate family and the girls I’ve picked out to be my bridesmaid and my maid of honor. How do I let her down easy?? Do I just not say anything and not invite her or be upfront and say only immediate family is coming. I don’t wanna hurt her feelings but again I don’t believe her intentions are true.

UPDATE!!!!

I told her that we’re only inviting immediate family and picking a small venue and she’s still insisting she’s going to be invited. She keeps brining up how her sister can make the wedding cake (hence having to drive it 4 hours away) and how I’m gonna be one of her bridesmaids (probably a tatic to make me feel guilty). I really don’t know how else to go about this. I’ve tried being nice. I think I’m just gonna have to either straight up tell her no or not say anything at all and have her find out in her own.
