Am I Over-Reacting?

So I have been planning for a week to go see my boyfriend who recently had to move an hour away for work (another thing is that both of our cars are in the shop, his from a wreck and mine just didnt like me lol) but we had been planning for me to come down tmro because my amazing friend is letting me use her car most of the day but I would have to leave my house at 10am, and he just texted me and was like idk if we can tmro anymore cause me and my friends are having a party and getting drunk and im not planning to get up till 1...I am so mad because we have been planning this for weeks and now he changes his mind
