The girl I like was accusing me of something? Help?

The girl I like was accusing me of something and I said why do I think I would have hurt you. She started not answering my question by try changing subject. So, I started saying that if I wanted to hurt you I would have done it before same as you hurted me. I told her she is important to me, and asked her if she trust me. Although she took time saying I trust you. She said lol, thanks. I started saying that I have done nothing and I would never do this to you. She said, to me get over it. I do trust you. Let's close this problem. Help! What's her problem.? I feel like we are married or something.
