Fi's brother aka best man tells fi that he is bringing this girl he just started dating. BM knows that he was not invited with a guest. Fine. that is no big deal at this point. This girl knows nobody. This wouldn't be a big deal either. So I tell fi to ask his brother who this girl would go with ( not sure if she has a car and our venue isn't around the corner) and where she would sit, etc. etc.. His brother was like with me. Ummm hello, you are going in the limo with us and we are going like 2-3 hrs early to the venue with our families. What is this random girl supposed to hang out with my family while we are relaxing and taking pics before the actual reception?I just can't even deal with this anymore.
