My best friend from childhood was devastated when I asked my future sister in law to be my MOH and not her. She flipped out when I asked her to be a bridesmaid and then took 3 weeks to give me a yes or no and by 3 weeks my mind was made up: I didn't want anyone in my wedding who needed 3 weeks to decide. I asked her to come as a guest and now she is apologizing and wants back in. What should I do??
