I was invited on a vacation and now my bf is now offended he can’t come

I (35f) have been dating my bf (Jax, 38m) for 2 years. My gay bff won a vacation for 2 at an international destination for 5 days. I actually met my gbbf while on this island so it’s very dear to us and we have lots of friends there (we both were there for over a year). He invited me to come. I asked my boyfriend if it would be weird for me to vacation without him. He said absolutely not. Since then, the vacation has come up 2 other times without issue (all while he was drinking but not drunk). Tonight, I went to go book my flights and he acted really strange about the trip. I asked him what was wrong , he was now weird about me going without him/ not even being invited. The package is for two people, and I have no right to invite him on the trip in my mind— since I wasn’t the winner of the trip…but he clearly is no longer OK with this happening now that it’s “real”. I don’t wanna miss out on an international trip where I get to revisit a place that I love with many friends, but I also don’t want to ruin my relationship.

Tl:Dr- I booked a vacation with my bff and my bf is mad he isn’t invited

Should I still go on the trip?
