Need some advice. An acquaintance of my FILs and a woman I did a Bible study with 16 years ago asked in June if she could throw me a bridal shower. I was perplexed by her offer given that I don't really know her nor do I go to her church. I thanked her for her very kind offer, but told her she didn't need to throw me a shower, though it was a generous offer. Apparently, she approached my FMIL about a shower in November. My FMIL gave her the names of people who to be invited....only 1 of them is invited to the wedding. I didn't know this happened until the other day and invitations are ready to go out and this woman has been planning the shower. There are 9 women invited to the shower and all are married. So, that would be an additional 18 people to add to the head count for the wedding. Here's the deal: I'm already just about at my limit as far as people go; I don't really know this woman; I don't know any of the women invited to the shower except for the one that's invited to the wedding already; and my FH doesn't have any contact with these ladies now that he's no longer working for the church. I know that etiquette dictates (and believe me when I say that I usually adhere to etiquette quite strictly given my personality and such) that I invite the women who will be at the shower to the wedding, but....I just don't have the budget for them and I don't know any of them. Thoughts?
ETA: Please know that I recognize that this woman's offer is kind, thoughtful, and generous. I do and am really humbled by her offer. It's just that I can't justify spending over budget (which I would have to do because we're toeing the line as it is) to invite 18 people that I don't know and that don't have a personal connection to my FH or his family outside of the fact that they attend the same church.
