Irritated & Baby shower gift was used and regifted

So, my sister in law had her baby last October and I went to her baby shower in mid September.

I'm not saying this to brag or act like we did the most but my fiance and I spent over $200 on her for her baby shower. And we were happy to do so.

We are expecting our first baby this August and we had our baby shower yesterday.

First reason I'm irritated is, we tried to keep our shower low key and just invited family and 2 close friends each. While asking a few people who were invited and hadnt given responses yet, we asked her if she was coming she said "No we just found out his Mom(her and her babys father live with his mom) had bedbugs and we dont want to spread it to you" we said NO PROBLEM and actually were thankful she was being thoughtful of not wanting to spread her bugs. Welllll, she showed up, SUPER late, WITH 4 extra people we needed to feed, and all of them live in the bed bug ridden home. We were opening gifts when they showed up, and that was taking place outside on the patio so we werent worried about getting the bugs but I'm still irritated at the fact she showed up knowing she could infest us AND everyone else there. My fiance says I'm overreacting 🙄

Well, anyways, she showed up with a pack of diapers and 3 gift bags, and upon entering made sure everyone heard her brag about bringing "so much" for us.

We opened gifts and finally got her hers. I started opening bag 1, it had loose blankets, onesies and random loose diapers and wipe samples. No tags on anything, and somethings had visible dirt on them. Moving along, as shes like "here's bag NUMBER 2, you're going to love it" it had a 3 loose pacifiers, kinda dirty shoes for probably a 2 or 3 year old sitting on loose 2 bottles, and to my surprise a nice looking sleeper sac still packaged and appeared unopened. Bag 3 comes along and I'm so happy it was almost over. Well..I guess she forgot what we gifted her because.. opened the gift and 2 different things we bought her last year were in it, no tags and dirty, shocker I know. It was an outfit set and matching bows and hats set. We ordered them all off etsy and its a VERY small chance she bought the same thing. Then there was a black blanket we had actually seen in her babies crib before in the bag COVERED in cat or dog hair, lastly there was a Where the wild things are book that I'm 90% sure I remembered her opening at her shower. But either way it looked in good shape so that was the only gift I was happy about from her. We finished awkwardly opening her "gifts" and shes just so full of herself at this point, because while everything she gave was used and dirty, she gifted "the most" items and she made SURE everyone realized and it was honestly humiliating because everyone could see how uncomfortable we were opening her her stuff.

Well they go in and eat a bunch of food and leave immediately after they played the shower games and got mad none of them won. We finished the rest of the shower without them and everyone left. And me being the early nester I am, I started unbagging things to put in for the wash before we put them away. My fiance was helping me and while we unbag and cut tags off all the gifts that are being washed I expressed to him that I was thoroughly irritated that 1 she didnt RSVP and then showed up with extras KNOWING they have bugs and 2 that her gifts were honestly embarrassing to open.

He told me I should be grateful, and that we just have to clean the things she brought and so on. His response irritated me even more. I am grateful for anything I'm gifted but when I spend SO much money on your baby because I care about and love you and you show up and give our first child dirty regifted possibly bedbug infested things it rubs me the wrong way and on top of that she tried to make the rest of our guests feel bad for not bringing as much as her.

I guess I'm wondering if anyone thinks I'm being overly angry or sensitive. I know sometimes we can make little things into big deals but I honestly feel a little hurt.

Also, I would like to add..which we both found kind of funny. Remember that sleeper sac I talked about?? She acted like that was a big ticket item. Well we unpacked it and underneath the front label where we assume she never saw because she never opened it, it said the name of the hospital her baby was born at...meaning it was a free item the maternity ward gave and she thought she would regift it and nobody would realize 🙄😂 I mean on the bright side..it was still packaged and taped shut, so we'll use it but..its still funny she thought she was being smart
