Just need to rant & some advice

My boyfriend and I hosted thanksgiving this year for his family. We spent all day cooking and all week cleaning and getting prepared. He has 3 siblings & 4 nephews. One of his siblings and significant other are vegan so we made sure to cook enough for them to have a full plate of food. Everyone shows up and the vegan couple show up with a FEAST (only enough for the two of them mind you) & they knew we were cooking for them. They come in the kitchen and start opening all our cabinets and drawers to find cooking utensils and start heating/ cooking their food…. Idk if I’m over reacting but I feel like it is very odd to go to someone’s house and start rummaging through someone’s stuff. They didn’t ask. They showed up with cookie dough that had to be cooked and idk but I’ve never showed up anywhere needing to cook something start to finish ? Like am I the problem? They have showed up at our house a few times and just open our cabinets to look for something and start cooking without even asking. Asking me where a certain pan is after already trying to find it in every cabinet. I just would never go to someone’s house and do that?

Another problem I’m kind of having -

Me and my bf live together and have for 3 years. Everyone kept saying “ Eli thanks for hosting” “Eli I like your house” “eli you did so good cooking”

Not acknowledging my efforts, and MY house as well. It’s a combined effort & I’m not sure why that goes unnoticed? It really bothers me. When they talk about it being HIS house I do say “well mine too” and then their reaction is like “well obviously”

I did have a good time at the end of the day but it just left me with a bad taste in my mouth with how both events transpired and how they keep happening.
