Why won’t my guy friend (crush) text me back?

I like my guy friend and started to have a crush on him since high school and he’s always dating these bitchy women and ever since I admitted to him that I really like him and texted him everyday, he doesn’t text me back. He doesn’t text me back right right away. What’s up with that? I’m afraid to ask him out because he may reject me. I really really like him. I used to just text him sometimes but now it’s everyday. He seems to get annoyed. I don’t harass him or anything. I know he’s busy so I just leave him alone.
We've know each other since age 9.
