The girl I like os driving me crazy

At first she always looked for me and talked to me. She even asked me to kiss her and we kissed, but when I told her I liked her she told me that I had misunderstood everything. So I ignored her for a month, but suddenly she texted me and told me she want to go out with. I was surprised. I went to spend the summer abroad and when I returned he did not tell me to see us. She saw me with another girl an texted me again. I told her that she was hurting me and she apologized, this wasn’t the first time she got jealous seeing me with another girl. I started to ignore her again and She don’t talk yo me, but always look bad at my friends.
