I have a group of friends with whom I used to hang out. One guy likes one of the girls, and one day when we were all together, he tried to flirt with her. She tried to give him hints that she was not interested in him and she took shelter in me. After a few minutes, she kissed me in front of everyone on two different occasions, to show him that he wasn't interested in him. We flirted a bit with each other and we enjoyed it, but she later said she did it to scare her friend away from flirting with her.
For context, I also have to say that she has always been very prone to breaking the physical barrier.
However, the next time we gathered, she seemed nervous around me, and whenever I talked to her, she responded with fast and short answers.
So, the next day, I went and met with her, and she again seemed nervous about my presence and she tried to avoid me. Before she left, I tried to reach out to her to tell her that we should talk some other time, but, when I tried to grab her arm, she became very nervous and shouted at me that I shouldn't have grabbed her before I couldn't tell her anything. She left immediately, so I decided to text her that we had to talk, but she replied instantly that she didn't want to because she thought I had a very ugly gesture grabbing her by the arm. I sent her a message explaining that I didn't mean to grab her, but rather hold her arm to tell her that I wanted to speak with her before she left and that I was sorry she felt it that way. Later I messaged her that if there was anything that I could do to make her feel better, she should tell me and that I really wanted to have a talk with her, but she ignored my texts and didn't reply to anyone. One of her friends reached out to me and said that she didn't like me grabbing her by her arm, and that probably it's due to traumas with her previous ex (he was violent towards her).
I don't know what to do.
