Opinion needed

I’ve been genuinely busy lately. I go to grad school next fall and I’m about to be even busier, I want to be able to spend time with my friends before I go. My boyfriend is mad I won’t blow up his phone or spend every day with him. I wanted to spend Friday night alone because I’m burned out with working and interviews for school, but he doesn’t accept it. What would you do? I’ve tried compromising by setting certain days to hang out, but sometimes that’s just not possible since I work and get tired. I feel like I can’t do anything correct and take care of myself.
