To bridesmaid or not to bridesmaid!!

**didnt know what sub this post fell in so here it is**

Y'ALL I need your help bad.

So I am getting married may 2018 and I have my maid of honor picked out and my bridesmaids but I'm stressing because there is a girl that I made friends with when we were like 6 or 7 and we instantly became best friends. But as we got older she hasn't really matured (she's 23) and is not all there socially. I love her to death but she's one of those people that is exhausting to hang out with. She's been in college in another state up until early this year so I haven't hung out with her a lot but she's made sure to keep up communication. Anyway, when I told her I was engaged she said, "great! I can't wait to be your maid of honor!" And bought me a wedding planner y'all 🙃 it wasn't expensive so I accepted it but I told her I hadn't picked my wedding party yet ( I hadn't at the time) And she kept making comments about how she can't wait to help me find the dress and taste cakes etc. all of which I've gone and done without her. I've picked my MOH since then and she's gone with me for everything. I think this friend has gotten the hint that she's not MOH but she still is making comments asking if I've chosen the bridesmaids dresses yet. I mean she's not specifically saying Have you chosen OUR dresses yet but it still sounds like she's assuming. I really do love her but I just don't know if the other BM's and MOH will get along with her and I think she'll try and bogart my time at wedding festivities (she'll be possessive bc we were each other's FIRST best friends) and just generally not get along with the party (like I said, a little socially awkward). It would be easiest to just have her as a BM but I don't want to have to stress during wedding festivities about whether she's getting along or not. I mean she'd be invited to the major parties (bridal shower, bachelorette, etc) so she'd be there anyway... what do you guys think 💭
