I have heard people say if a guy does not reply to your message it is because he doesn't like you. Well ok fine, why don't guys just say it straight out 'I am not into you' instead of getting a girl's hope high.
Most guys have said it just seems cruel to say straight to a girl that they are not interested so they rather slowly cut off contact and hope the girl gets the hint that they are no longer interested. But surely a guy would see this is more cruel than actually saying I am not interested.
I texted a guy once who then didn't reply, I thought ok he did say to email him (we were living quite far from each other). So I thought ok then I will, he then replied back to my email and I wrote him back and he never replied. I felt like he did this just to hurt me, to get my hopes high and just crush them.
