Why he won't text me back?

My bf found out I was being unfaithful and dumped me then said he did t wanna break up I told him what I did was stupid n I love him but I had to go I was in class and couldn't text then he sent a text saying I apparently don't care n now he won't text me at all I'm confused and feeling depressed I am really sorry n I love him to death

you are very young and looks like you did that in order to find out if you would get caught.the cheating.you did.do you still care about him?can you win his trust back and never test the relationship like that again?
Can you do that?

You hurt him and he's processing it. If you've called and texted and he hasn't responded, then you have to give him space. The ball is in his court. He'll contact you if he wants to work it out. There's not much you can do at this point... except learn from your mistake.
