My boyfriend is not texting me anymore, why? Please help i need to know?

I think you might have done something that has caused him do this! 

Anyways if you've done then just keep saying sorry  to him and if you've not done then go and talk to him politely and ask about the matter. Or just message or text him to tell u what happened then maybe he will tell. Because tho he isn't replying he's still reading them so maybe his mind changes!
