Am I wrong to be sad/mad

So my boyfriend and I both go to the same college (together abt 6 months). I’m moving out of my apartment this weekend because my roommates and I are going to live in a different place for this new school year. But we can’t move into the new place until august 21. So for 3 weeks I’m going to live at my parents place about an hour and a half away. My boyfriend lives here full time.

We don’t see each other during the week that much this summer because we both work full time (he works a lot of overtime too). So this upcoming weekend would be the last time we’d see each for 3 weeks, which was no biggie like we can do that. And most of the weekends this summer it’s been after we are done working on fridays we hangout/spend the night together at one of our places. And so I have to be out of my place by noon on Saturday so I asked him if he wanted to have a final sleepover at my place Friday night and I did already assume we were gonna be together that night. And he said he can’t he’s hanging with the boys on Friday, but we can hang after he gets off work. And that upset me because I’ve been thinking we were on the same page about spending that time together and like he’s the reason I’m even staying this long. I don’t have a problem with him hanging with his friends, but like he has Saturday night and 3 weeks he can do that??

I didn’t tell him I was upset because I don’t know if I’m just overreacting. Like he still said we can see each other, but he has an inconsistent schedule so he might not get off til 6 on Friday and then we have like 2 hours together. Also part of me was hoping he’d still wanna see me while I’m not living there like I’m not that far we could do a day thing

Idk I don’t wanna be mad/sad by this but I just want effort
