Is it mean if i don’t have her in my wedding?

Hi there all,


First of all, I know that this is my wedding and I choose who to have with me on the day... but I’m in a little dilemma.
I met my close friend from college 4 years ago, over the course of our friendship we both would discuss our weddings and etc where one day we both said we would have each other as bridesmaids - I didn’t really take it serious. She just got engaged in October 2019 and I have been ask to be a bridesmaid. We live on other sides of the country now and keep in chat maybe every couple of months. I have just got engaged myself and Im not sure what to do about my own bridal party.
Is it the “kind, decent” thing to do and ask her to be in my wedding because I’m in hers or is it rude to not ask her at all?
I did always just want my sisters but I don’t know if that will be enough for her - I feel she will get offended and make a big deal about having each other in our weddings.
Anyone else ever been in this situation? Any advice?
Thank you xo
