Planning to leave my boyfriend of almost a year

I'm going to be going through some major life changes (having to do with future success) in a week and onwards, and for a month or so I've been planning on how I'm inevitably going to have to split up with my boyfriend. He's 2 years older than me and we are from different places (30 min drive). I just don't know if I'm feeling the relationship anymore. We started dating due to common interest, and I guess being in the right place at the right time and circumstances. But even that interest I let go of a bit to let other things in, but he's still super devoted to it. 

(Another little point as to why I'm not as much of a fan of him: He's really bad at making plans to go places for dates or whatever. He never makes an effort; I'm the only one that pitches anything. I mean it's okay to want to stay home and cuddle, but not every single weekend. And like, I'm not just gonna be his saturday-suck... I had to point it out to him and he's been making more of an effort, but I'm still not totally feeling it with him.)

And it sucks to say, I eye some other guys sometimes. I even came up with new "types" or whatever to choose from, even though those probably won't come to fruition cuz I'm so infatuated with...(fill in the blank I suppose). However, I'm still a teen. Since the beginning, I could tell he wanted something a bit more long-lasting, even though he's around my age and it's not really the most realistic thing ever. But that isn't totally what I'm about, and that's something that I've been realizing within the past half of the year. 

I've basically had a lot of my childhood stripped away from me due to various situations, and I've been reflecting a lot about it recently. I want to focus more on myself, my hobbies, and what I want to do. 

The thing is I still really care for this guy, and he's a really cool and genuine person. I've also helped him get through some times within the past year when he went through conflict, such as the absence of his father. Something happened in January of this year where I broke up with him due to external factors including stress, but I couldn't handle it anymore and we ended up getting back together that same night. 

I'm not saying that I'm great in this situation, but I do feel really bad for him. And I'll probably feel even worse when this plays out. It's something I worry about quite a bit and sometimes lose sleep over. 

I became super hyper-fixated over something a couple of weeks ago and just used it as a coping mechanism, and suddenly I barely cared about what he did, and parts of me believed I didn't care about him at all. And I know it sounds bad, but that's the only way I can try and go about this. I hope that with these changes coming up it will allow to put the relationship on the back burner and eventually away. It's not the most realistic approach, but what else am I supposed to do?

I guess the first step was telling my dad, and writing about it on here. Maybe that's progress. Thoughts?
