He proposed at midnight NYE!

I am so happy and excited! I cried so much as I was screaming the countdown with everyone and he got down on one knee. 
Besides all that, I haven't even started wedding planning and my girls want to know who's maid of honor/bridesmaids and so on. Who knew it was so difficult just choosing a maid of honor? 
One girlfriend I feel would be pissy if I didn't pick her because she always reminds me that "if it wasn't for her, I would've never met him"
Then another other I talk to more than anyone. We've been friends for 10 years but she's got 3 kids and I don't feel like she would have time for being my maid of honor. 
The next girlfriend I've been friends with since 6th grade. We've never had an argument. But we really haven't hung out more than a handful of times within the last 5 years. She really wouldn't be mad if she wasn't my maid of honor and honestly I don't think she's the kind of person who would want that responsibility. 
How are you handling this?
