Guys, Do guys really hate insecure girls?

Anonymous
So me and a guy were flirting, then he did something so I kinda wrote "sad", long text messages with questions. I later apologized and he told me it was fine. IRL he acts normal and shows interest. He's the one that talks to me first and teases me etc. but he doesn't talk much through text.

Next time I see him I'm planning to tell him that I'm not a crazy girl who get's annoyed and types long messages. I was just insecure and wanted to know what I had done wrong. (I don't see him as much anymore because he had to switch schools just recently. Before, I saw him every day. And before he left our school he felt a bit off. I don't know.) I'll wait a month from now before I even contact him. He even forgot his headphones at school and a few other stuff so I'm going to tell him I'll bring it to him. Hopefully he wants to see me then. But that's in a month... Need to keep distance... haha.

Will he get completely turned off if I tell him that I'm insecure and thought I had done something wrong and blamed myself.. That's why I wrote long messages? Because I've never been like that before. I don't know why I was doing it. It won't happen again because I'm not like that and I'm ashamed. Is it ok for me to confess that?

He's kinda shy and he's said things to me that make it seem that he's also a bit insecure... He's said he used to talk to girls before because he wanted some kind of confirmation from them etc. But sometimes people turn down people although they don't realize they're the same so... yeah.

I should might add that when we met I was shy and uncomfortable, and he told me it was okay. He told me he felt the same... So maybe he doesn't have a problem with me being insecure? I don't know.
