Boyfriend wants to go on our first vacation alone?

So I am in the process of getting a new job and it's cutting it close with a vacation I planned with my boyfriend. My boss still hasn't sent me any timetable details and my boyfriend is going around freaking out about how we don't have enough time to book a hotel anymore and all that. He's demanding I hurry the boss up despite him frequently updating me, so ofc I find hurrying him up pointless. Then last night my boyfriend goes on a whole rant about how important it is to him, that I have no respect for him or *his* plans and his money and that he doesn't care what I do, he's gonna go on that vacation by himself. That personally fucking struck me because what do you mean you're going on *our* first planned vacation by yourself? And like I trust him to be in a whole different country by himself. Im seriously considering breaking up with him if he ends up booking a hotel just for himself, but what should I do? It's impossible to have a conversation with him without him going on a whole rant and getting defensive.
