Asked maid of honor to step down

I'll try to keep this as short as possible. So I'm wondering if I did the right thing. Recently I asked my maid of honor to step down from the wedding because she was causing me so much stress. I'm only having the maid of honor and one bridesmaid in the wedding. I wanted to keep it small. The stress with my moh all started with the bridesmaid dress. I told her she could go to the bridal store and pick out any dress she liked as long as it was the color I had chosen. Everyone has a different body type so I didn't want her to get something that wasn't flattering or that she wasn't happy with. Her exact words were "I'm never going to like a bridesmaids dress so just pick one because I don't have time to be trying on dresses" which I felt was rude.
Then it was time to start planning the bridal shower. I had no idea about the shower because I honestly didn't want one. But a friend felt I should have one and contacted my moh so they could get the party planning started. My moh called me yelling and swearing saying "I don't have money for a f****ing party" a party I didn't know about until that moment. That really hurt my feelings because I didn't ask her to do anything for me.
When we talked about the wedding the only thing she seemed concerned with was how much weight she'd lost and how she needs to look good in the dress. She always would say weddings are a waste of money and she's going straight to the courthouse to get married. I needed to vent about wedding planning and all she could do was make me feel worse by saying weddings were stupid.
She finally did get together with my other friend to get the bridal shower party planned. So 2 weeks before the shower she goes to "help" my friend set up but instead brings her work laptop and takes calls the whole time. Needless to say she did not help at all and my other friend did all the work. She literally complained the next day about how it was a waste of her time to go help because no one told her what to do.
Other people in the family contacted my moh to ask if she needed help with the party but she said no. So she wasn't doing anything at all and just decided my other friend should do everything and not have any help? I don't get that.
Everything was about her. She flat out told me she wouldn't be throwing me a bachelorette party either. I don't care about having parties thrown for me but I do feel that there's a nice way of telling people you can't do something. I don't think it's because of money. She has expensive taste and spends money on herself all the time. So I'm not sure why she didn't want to do anything for me.
I tried to talk to her about how I felt but she just yelled at me and didn't let me talk so that's when I decided to tell her to step down. She didn't seem to care and just said "ok" which seems very childish. Do you think I did the right thing? Isn't the moh supposed to be there for you and not yell and swear at you?
