so i just recently got engaged

and of course had my Maids already picked out, my best friend, 2 baby sisters and fiances sister and cousin. I asked my best friend to be my moh because she is my other girl half . when i asked her my fiance and i took her out to a nice dinner and i made her a picture fame with basically a love note and a picture of us. she is not the kind of girl that has been planning her wedding since she was 5 or really a "married" girl but knows i am. we are the type of friends that even if we dont see or talk to eachother every day nothing changes.
my issue i guess is that since i asked her (about a month ago) we havent really talked or anything and doesnt seem to have the excitment i was hoping for.
i dont know if this is just the norm for us or should i expect her to get pumped i guess? i wsa thinking of just havin a sit down to let her know that i picked her because she is an imporntant person in my life...even though i did write her a "love letter" and ask her if this is something that she is really wanting to do.
