One 'no' would suffice you know

Ouch

There is a chance it my just be shyness...

maybe your crush is just sooo shy and needs to grow some balls

But was she laughing? As long as there was no laughing, there is still some respect there... and maybe a chance.

Think about how people act when they actually like someone and are trying to "play it cool" but actually make it painfully obvious. Seems to me like he did this

This is what a lot of people do when they don't want to admit it their feelings, you know. Either that, or she's just not very sensitive towards yours.

Rest in RIP in Peace.

Or he is a bad lier and he was trying to make it sound like he doesn't like her at all

damn. sorry, OP. AND I FUCKING KNOW YOU AREN'T THE OP

I think it depends on the way he/she said it.
