Any advice?

First of all, I’d like to thank you all for taking your time to read and provide an advice on my problem. My boyfriend and I have been dating for 4 years. We started dating at our junior year in high school and went to different universities, which is 1-1.5 hours apart. During the first two years we’d meet up almost every weekend or so when driving back to our hometown. But now, we usually don’t have time for each other anymore, and for some time I’ve been feeling like the spark that I use to feel when I’m with him is beginning to slowly diminish. But its not so much about the distance; I am someone who works very hard to achieve the grades I want, especially since I have ADHD. My boyfriend is a smart guy but somehow he ended up slacking off and his grades started going downwards. His family doesn’t seem to give much motivation to him so I try my best to give it to him. But I feel like I’m treating him as a mother than a girlfriend. He keeps changing his career goals that it makes me feel uneasy about his plans in the future. He hasn’t joined any clubs until last year in the fall. He’s also now been busy with the club that we have less time to see each (maybe once every 3 weeks). And when we do see each other, we don’t hang out much: our time is just usually when were driving back home. I’d hope he’d make some plans to hang out (I’m always making plans to hang out and would like it if he did the same), but doesn’t really. I mean don’t get me wrong, he’s a good guy who loves and respects me, a gentlemen, and my family loves him. But every time he says he’ll prove me wrong and get better grades, it doesn’t come out that way. So I think what I’m getting at is that I’m disappointed that he didn’t turn out to be what I thought he’d be. I am afraid about breaking up because I do love him but I also don’t want to feel unease and disappointed. Help please?
