Hi.  I was supposed to have 4 bridesmaids and my fiance was also going to have 4 as well.  However, one of my bm had to back out and 2 of his groomsmen had to back out.  So I will have three and he will only have 2.  I don't think its a big deal.  Personally, I think its more important to have those that you love and love you and you want to share your day with by your side.  If that means 5 girls for you and only 2 for him than that is great.  when you look back at your photos you probably won't think “that looks terrible its uneven” but instead you will probably say “so glad they were there with us”.  hope that helps some!
