I am getting married on 9/16/17. We are trying to keep our wedding as intimate as possible, not only for the cost, but also for the feel of the day. I have a large family, so that has taken up a good portion of the guest list. My friend and former coworker is getting married on 10/14/17 (which also happens to be my birthday!) and she sent me a save the date. I plan to attend her wedding. I would love to invite her to our wedding, but if I invite her, I would likely have to invite 3-4 other people in the same social circle that will be at her wedding one month later, otherwise there will be some intense awkwardness. There is the possibility that we can add everyone as some from our guest list will not be able to attend, but I feel badly that I've already taken up a large portion of the guest list with my family and my fiance has a smaller portion of it.
