I only see my partner once a week

Hi guys. I (24 F) only see my (28 M) partner once a week, we live in the same city. He’s studying and is in his last year of his bachelors degree, which is important to him. I just feel pretty alone right now. We’ve been dating for four months, and recently we’ve only been seeing each other once a week, when he’ll sleepover then leave on Saturday. I know he’s busy with school, but I can’t help feeling very alone In the relationship. He’s not a big texter or caller, so we will speak once a day, but only a few messages (like 3-4). I’ve mentioned and discussed to him that I feel lonely but he doesn’t really seem to think much of it. It’s making me resent him and think that he’s not putting any effort into our relationship/ doesn’t care to. I just feel literally single every day other than when I see him. When we do see each other, we don’t do much because he’s also broke. He doesn’t take me on special dates when I see him, or do anything of that sort, we mostly just chill at my apartment. I know some people can become really drained when it comes to university though. What are your guys’ thoughts/ how would you deal with it? Would you stick it out?
