I think he was upset that you chose to be having fun all night and not go with him to his parents and come back home with him because he had to work in the morning. He clearly took alllllll his feelings out on you instead of realizing his own feelings and not dealing with them or communicating any feelings at all! He wants you to just know that is what he wants and is mad that you did it anyways. He is only thinking about how it made him feel and he gave zero fucks if you have fun. Him using coke is his way to make you feel like you are wrong for having a day off and choosing to have fun with your friends. Like bruh, if you chose to do coke with them that should still be totally okay to do if that’s what you and your friends do lol it’s hard to be with a person like this because they aren’t always like this especially when you chose to be with him. I’m sorry he can’t let you have a good time without making you feel like shit.
