I'm confused on how to move forward.

I (M16) just had my first relationship end. She said that she wanted to focus on herself and that I was perfect, but she wanted to be alone. I know it might sound pathetic that I'm so torn over this break up, the sentiment over high school relationship being sour from what I've seen, but this was my first relationship and I truly did love her, and I think I still do. The relationship didn't actually last that long, just shy of 2 months (i know i know it sounds pathetic). Anyway, I think I'm definitely feeling better since the initial time of the break up, but I'm still going through it. I watched a few videos on how to get over break ups and a few of them say to list out things you didn't like about your ex to help you stop looking at them with rose-tinted glasses. The problem is, she was genuinely amazing. She was so sweet. She was so considerate, like if I did something for her, even as simple as making her food, she would ask if it was ok if I did it first. She never was abusive in anyway, mental or physical. The only thing I can think of was that, I'm an affectionate person, and she's not, at least in public. The problem was we only saw each other at school. But when we texted, her affection would show there. Again the only thing I didn't like was that she was affectionate with me in person. However, she said that she doesn't feel comfortable being affectionate in public because of her anxiety. However, if we were somewhere private, like she said, her room, then she would be comfortable with being affectionate. The problem is we never got that chance so whatever. Anyway the main problem is that I can't see anything she did as wrong other than just one thing that kinda is understandable. Alright I'll try to end this here. All I'm saying is that I need some outside input to help me stop seeing her with rose-tinted glasses.
