I don't understand, Why did she stop replying after all this?

there is this girl that i have been talking to for about a month. I ALREADY told her how i feel about her and she replied:

"Aww, why didn't you tell me earlier?, i think ur great and i would love to talk to you"

A few weeks later a friend asked her if she likes me and she said

" no not really cuz i don't know him "


I'm so confused....


Also we have not met yet. It's been like 5 days since. We've texted and i have sent her a few messages up to now. The first one i assumed she wasn't interested and said i wouldn't bother her anymore. The next was about what i think of her. I told her i really wanna get to know her better and that there aren't many girls out that like her. The last was about her being able to trust me and that i will leave her alone if she tells me to.

..... what can i do?

Last thing she said to me was "Wyd" and that was about 5 days ago....

Ever since then i haven;t been able to stop thinking about her, its weird because like i said we haven't even met..

I don't understand, why did she stop replying to me? Did i do something wrong? Please i need help, i'm confused and i don't want to forget about her. She seems like a really cool girl and i want to get to know her better. I can tell even though we haven't met yet that she deserves a nice guy like me that actually likes her
