exes (final development??)

I have what I believe to be a confirmed timeline of what happened.

She broke up with me. Somewhere between 5-20 minutes later, she asks out her boyfriend. They were probably in the same room when she broke up with me.

I understand obsessing over this won't help. It will only make it hurt more in the long run, and yet I still keep trying to understand.

When did she realize she stopped liking me? She still wanted me as a friend, and maybe she still does like me, but he clouded her thoughts more. She must've been feeling this way for a while if she moved on so quickly.

She had liked me since 5th grade. For reference, we're ending 8th now. She got with me roughly at the end of 7th. We were fine. She loved me all through then and for what? To leave me for a gender she didn't even think she liked?

I'm so done with love.

She acts like everything is okay when she giggles off to me during band and I just have to endure it. I'm planning to tell her this weekend that I can't handle being her friend anymore. That I can't look at her without seeing what we planned, or her kissing me, or the feeling of her cherry lotion on her hands.

I miss her, I do, but I need to let it go faster.

What could I possibly say to her? Or better yet, some kind of silent revenge? (I saw her talking to my ex today at lunch, and last I checked they hated each other. I can't do confrontation 😭)
