I'm getting married in October and chose my bridesmaids around Christmas time. I asked my sister, my fiance's sister, my brother's girlfriend (who might as well be my sister) and my three best friends (we were college roommates and continue to be very close). Recently, my mom informed me that my cousin was extremely upset that I did not ask her to be a bridesmaid. She and I were very close growing up, but haven't really spent any time together over the last ten years. The only time I see her is at the occasional family gathering, and even then we don't really spend much time together. My cousin, however; is so upset that I didn't ask her to be a bridesmaid that she will not be attending our wedding at all.
I feel bad that this is probably going to create some drama in my family, but at the same time I think she is acting extremely childish.
Am I wrong for still not wanting to ask her to be a bridesmaid?
