Why did she block me?

on Instagram, I made an account with fb and I added some people, I added her and I went through my list and noticed she wasn't there. I searched her name again and she didn't pop up, I saw her name in someone else's thing and I went to hers. I know when they block you, you can't follow them. I tried to follow, it would just turn green back to blue. After a while though I decided I didn't want my fb profile as the account. which iss what i used to sign up, so i deleted it. and made another one with my email. I re-added people and her. after about a week I went to search and find other people, her name was first and i accidentally clicked on it. it loaded but no posts/pictures and I wasn't followed to her. I clicked follow and the same thing! several times and it went back to blue. So she blocked me on my second account too? why? whats with her? even on the second one she did it, I don't understand. does she hate me?
