Couples Shower- am i the rudest person without knowing?!

I have to start this by saying I feel HORRIBLE. I made a huge etiquette faux pas and didn’t even realize it. I got engaged a while ago. In my family I am the eldest daughter/granddaughter on both sides. The last time a wedding happened in my family was in 1991. My fiancé is in a similar boat, he’s the eldest son/grandson and knows nothing about weddings. That’s to say, planning a wedding is completely foreign to us both. He mentioned a while ago that his mom was excited to host people at her new house she just bought and can’t wait to have people over for “wedding things”. Knowing this, and because his mom is wonderful and loves us and I love her and I want to include her since I feel like the MOG can get left out, I asked if she wanted to host the couples wedding shower and she said she was happy to do it and was excited to. I DID NOT KNOW THAT IS SO RUDE OF ME. I didn’t realize the two showers I’ve been to, the couple/bride were not the one who initiated it and that usually someone offers to host you one. I didn’t know until I started reading threads about showers. So now I feel like a gift grabby b***** when all I truly wanted was to include my future MIL and the two showers I’ve been to have been very chill hang outs with games and some gift opening. I want to crawl in a hole and die I feel so shameful. I apologized to my FMIL and she told me she was so happy to host and didn’t think twice about it, she’s truly an amazing loving woman. But I can’t shake this greedy gross feeling. Mostly venting my shame but should I do anything else?


Also if you shame me, I get it. But before this is only been to two wedding showers and I’ve never been to a baby shower and I’m just dumb.
