BOYS, What does this mean.. If a guy...?

I was texting this cute kid, Collin. Me & him were talking for three days and he was being so sweet, saying I can't wait to hang out with you and cuddle , you're so cute. And all that stuff... Then we got into this conversation about weed, he said he's never done it and he's never going to. He asked if i had, i told him honestly i got pressured into it ONCE & tried it once. But I'm totally against it and i regret it and will never do it again. He was mad, at first, but then we had a normal conversation... then he stopped texting me. NOW HE'S IGNORING ME. It's been a day , and no texts. He doesn't answer mine. He ignores me on facebook. It's frustrating. I want to cry. Please help me!!
