Happiest of times my @$$

So my best friend was asked to be ny mateon of honor. It has honestly been a nightmare. She just got married and seems to want total control over my wedding planning details. My fiance and i want a jack and jill for many reasons. She flat out refuses to help plan it as she wants to do just a bridal shower. Shouldn't this be the decision of the couple? Then she has her dress and my other girls don't so because i had to change the time of the girls going for dress she got even madder. I honestly didn't think it would matter as she has a wedding to go to that day. Oh and to top it off she lied and told me that the girl worked her time around my girls dress appointment. I just feel anytime i share something she shoots it down. She was also super pushy for her now husband to be one of the groomsmen. It's like I'm totally done with my ideas getting shot down or being told qhat I'm planning is dumb. Am i in the wrong to feel this way?
