Here’s what I see: she said you are stalking her and being creepy, you explain why it’s not. In her head you ignored it, so she got her friend involved to tell you the same thing, you ignored it again. Now she panics because two people have told you the same thing and you have ignored both people. From her perspective you are a danger, regardless if you are or not, which is why she denied sending her friend to text you. It is something to remember for the future, if two people say the same thing it should be looked into as it could be true. I have lived with Autistic people that have trouble with social cues, so I have some idea of what went wrong.
Do the side quests before the main quest as some of the side quests get locked off when you compete main quests.
