Relationship advice please

Okay so a little backstory, I'm 20 years old and have super strict parents. We always go on holiday in december for Christmas and new Year.

So I've been dating my boyfriend for 3 years and for the passed 2 years he has been coming on holiday with my family in december for free, not contributing to food or anything ( which is fine) .. now because of covid we weren't sure if we will be going in december but my dad just confirmed that we are however my boyfriend might not be able to come because of university. Anyway, hes upset that I'm going now and hes telling me that I should stay home. Hes also upset that my sister and I were planning to fly down a week before my parents got there and he says he doesnt understand why I have to go so early and that I should stay home .

Last holiday he left early and flew home to his family and I stayed for christmas, he fought with me when I went to the beach and when I went surfing because I was doing it without him. He also told me that he expects to be put first before my family otherwise our relationship wont work. Everytime I go out he gets upset with me and I've given him no reason not to trust me. Last week Saturday I had a lunch for my sister's kitchen tea and he was fighting with me and barely spoke to me for like 3 hours.

Another instance is that my cousin has moved to Portugal and she said that I should come visit soon and we can do a roadtrip around the whole of Portugal, again ,when I told my boyfriend he was angry with me and said "fine then I'll go with my cousins on holiday"to which I replied that's fine I dont mind we have separate lives too.

Just looking for some general advice please.
