my boyfriend isn't acknowledging that I'm leaving

I'm not going far for school, I'm still going to be in state, but I'm not going to just be up the street. I'm staying in a dorm that's at a "maybe you can come home on weekends sometimes and if there's an emergency" kind of distance, which freaks me out because I don't want to be far from home. I wasn't initially going t stay on campus because I was super expensive but I got a scholarship that paid for everything, room, board, tuition, even books, and I also received additional scholarships on top of that, and even though I'm proud of myself for getting these scholarships (I mean no student loans how lit can it get) I was slightly disappointed because I knew that the situation was going to turn into "well since we don't have to pay for it, you can stay on campus now" which it has. I didn't want to share a room or share a shower with anyone, I didn't exactly want to leave home. but my mom thinks I'll regret not having the experience (personally I don't think I will, I'm not a social person, I like personal space and alone time, I know my roommate from middle school and she's sorta high maintenance and I feel like that may cause conflict, also there's no air in the dorm!?) but we agreed I would try it out for at least freshman year because we can't have cars on campus, but I'm still trying to come to terms with it. I leave on Thursday, and I've been avoiding packing for it or even really talking about it so it's a lot closer than it seemed. it's kinda blindsiding me. but because I've kind of been brushing it off, it also keeps going over my boyfriends head as well. every time it's brought up he's like "oh, you are going to stay on campus, I forgot" so he's not realizing that this is my last weekend home before I officially move in. I wanted to spend this Saturday night together, but he's with his friends. he went away with them on a boys trip just last weekend too. he was here last night, and he couldn't spend the day with me because he had to go to work (completely understandable) and then he already promised a friend to do a favor for them (also understood) and then we were going to do something with a mutual friend from the gym but they cancelled. so I was thinking even better, just him and me. but by the time I text him to talk about this change of plans he just decided to hang out with his friends since he was already there. and my feelings were just a little hurt. I know there wasn't any malicious intent, and we have dinner with his family every Sunday so I'll see him tomorrow, and I know that later on he's going to beat himself up for not spending as much of our last weekend together as we could've. but I just wish he wouldn't continue to not acknowledge that I'm not going to be here everyday like I am now. when I went away for just three days for my orientation he was up my ass when I came back and the whole time I was gone any time I checked my phone he was leaving me a message saying how much he missed me, and he wouldn't stop saying it when I came back. I wish he would stop letting this go over his head! if you're going to miss me so much, spend time with me while I'm still here! since he was already with his friends I didn't bother saying "oh well… do you think you could come hang out with me instead?" because that's selfish, if I was hanging out with my friend, and she just got up and left me to go be with her SO I'd be pissed. I just wish he would've thought about how he would divide his time 😔
