My ex

So I ended up breaking up with my partner. He had told me that we needed to take a break, I don't know why. I don't know what I did, I think that it's a me issue but he didn't tell me that I did. He told me the opposite and said that it was a him issue but I doubt that. I was being my normal self and he has never had a problem with that so I don't get it. I asked him around three times if he wanted to break up and he didn't answer me, he left me on read so I ended up just breaking up with him. I know it was fucked up but he said it was because he was confused, I know it was about if he liked me or not but it doesn't matter to me at this point. I've been going through a lot and that wasn't making anything easier for me. It was making me feel like a really bad person and that I was doing something wrong so I ended it. Then when I was on the way home from school on the bus on Thursday I heard from around 3 to 4 people that he was seen holding hands with another kid. Like I know the way that I'm looking at it is some elementary school shit but in the same way, I knew something was up way before any of this stuff happened. What I mean is that he started to ignore me and not want to answer my questions or hang out with me anymore, and mind you he was really clingy, so I knew something was up. I guess everything happens for a reason. But yeah, that's how my week went.
