<human>: Can you provide a brief rundown of the text in within 3 sentences?

My mom, future MIL, and bridesmaids are planning me a bridal shower. I'm so grateful for everything they are doing, but it has quickly become something I never would have planned for myself (if planning your own shower wasn't such a huge etiquette breach!)

Originally, I didn't want a shower at all, but everyone insisted that they wanted to throw me one, and that it would be easier to get gifts ahead of time than haul them all home from our reception venue. Okay, that's fine. I won't disagree that it's awesome to get presents, of course, and my MOH and future sisters in particular are so excited to plan all this for me! :)

I asked my MIL if we could have a Jack and Jill shower (that is, both men and women are invited) and she immediately shot that down.  PUTTING ASIDE non-binary genders, dated sexist beliefs, etc, I know that shower guests are typically mostly your aunts, grandma, etc. But I wanted my fiance to be there with me, and maybe some of his groomsmen to liven up the party. That's out too.

So now I'm having this all-girls bridal shower, just for me (my fiance's name wasn't even on the invitations) and I don't know how to interact with everyone - there's going to be so many people there I've never met. MIL added a few dozen people to our guest list and those ladies are coming! Plus some of our registry items were specifically added by my fiance. Am I supposed to say "oh he was so hoping to get this! I wish he was here to see it but I wasn't allowed to have anyone who identifies as male at my shower!" ***Obviously I wouldn't actually say that...
<bot>: My upcoming shower is huge and completely different from what I would have originally wanted. Is me sitting there alone and opening OUR presents the norm? How do I thank my fiance's second grade teacher for coming without seeming gift-grabby?
