What do I do about this girl I like?

She's a friend. I wanted to build our relationship before I let her know I like her, but she ended up dating another guy who she barely knew. I got over her, and told her the truth about how I used to like her but didn't anymore, and she said it was good cause she sees me as a friend. After she decided she didn't like the other guy (it was only a week later) I realized that I liked her again. I didn't tell her that, but we text every day and hang out pretty often. I want to be with her but I also don't want to ruin our friendship. Should I tell her I like her? Wait it out and see where it goes? Should I drop hints? Tell other people? Any advice at all is helpful!
