Don't text her for a while. If you apologized then that's the best you can do for now. Be nice to her while youre working on the project but don't make an effort to talk to her outside of school for a litte while. She's annoyed by you and trying to force it will only make it worse. Give it time, and hope you can start to repair things a bit just by being nice and giving her some space. It'll take some time, but the more you bug her the longer it will take.
