:( have I made a mistake?

Hey guys. I just broke up with my boyfriend and I don’t know if it was the right thing to do. If you haven’t read my previous post, we have been going through a rough time and he has been acting really immature lately. He is usually very clingy and I don’t usually mind it, but it bothered him that I wasn’t. I explained to him so many times that I was just an introvert who wasn’t the same kind of person as him, but he didn’t understand. Last Saturday he told me that we should take a break. I had no idea how long it would last and I was pretty emotional the whole time because i felt like it was completely my fault. He didn’t even look at me while we were at work the next day. Then, 2 days later he texted me just as I thought he would... he said he was sorry, but it was clear he still didn’t understand why I wasn’t as clingy as him. It was the hardest thing I’ve ever done to tell him that I think we should just not get back together. It obviously made him really sad; my mom saw him at work last night and he started crying. When I broke up with him i told him that this is probably the best thing to do anyway, because this is our senior year of high school and we’ll be in college away from each other soon; and it would be even harder to get over a breakup then, when we’ve gotten even more attached to each other. I repeated this to him so many times that I myself forgot the reason I even broke up with him. I think he did too. In my head, when I think of college as the only reason, I think, that’s ridiculous; we love each other so much and we should definitely spend our remaining time together. Who cares if it’s sad in the end? I think he thinks that too but he told me that since he loves me he will let me go and he wont fight for me to stay. That makes me wonder if he’s even thinking about our argument at all, and the reason why I’m not as clingy as him. Meanwhile, I’ve been a complete mess and I’ve broken my own heart to leave him. Every time i think about all our amazing experiences together, I see past the bad parts of it and i start to miss him so much. I think about all the things we had planned in the future. I was so excited to have Christmas with him. And since he is a ginger and I have brown hair, we were going to be Ron and hermione for Halloween. When I get a car we were planning to escape to the beach together for a weekend. I am crying right now because I miss him so much. Have I made a mistake ? :( is it ok to see past the bad stuff /do you think he will learn and change his state of mind for me if I get back together with him? I’m afraid I wont ever find anyone as kind, sweet, and adventurous as him.
