Introvert vs extrovert

In short I typically am very introverted and I’m not a big fan of being around people who I’m not very familiar with, my boyfriend on the other hand loves parties and loves making new friends. Since covid began he started going to more parties(bonfire/house parties) with his friends since the bars were closed I went to a few but generally didn’t enjoy going so I stopped. I was content staying home and having some me time but sometimes I did get a little upset about spending my Saturday nights alone though he would message and check in on me and ask if I wanted him to come home various times throughout the night I just didn’t want him to be annoyed that I wanted him to come home earlier than he wanted.

New Year’s eve is tomorrow night and he just told me his friend was having a party and he was planning on going, I was pretty noticeably annoyed and I just went “...oh ok” and he asked if I wanted to go and I just told him flat out “no” so he told me that we could just stay in and hangout if I wanted, which that is what I would prefer. But my issue and what I’m asking advice on is because we are also young and I am scared that me not going/ being annoyed that he’s going is going to make him have some resentment towards me putting a damper on his young party years I just really don’t know what I should do.

I have talked to him about this many times including tonight and he always tells me “I’d choose you over any party 1000 times over” but I still am scared that he’s going to resent me.
