What does it mean when he NEVER texts you back?

Does he talk to you outside of texting? If he's your boyfriend, you should be close enough to ask him about it. If not, it could probably be that he is indeed busy, or he just doesn't like texting.

Don't try and text him continuously, though, if you want to talk to him. This could drive him away. If you guys have a happy relationship, then you should be able to just ask him about it. It honestly could be because he doesn't like texting, or he's busy. if he's involved with after school activities or something like that, or if he's hanging out with his friends, he could forget to text you back. I know that I do that all the time; I look at the text and then I set down my phone to do something, but then I forget to respond.

It's probably nothing, but all you can do is just ask him about it if it's really bothering or concerning you.

Good luck :)
