I don't know what can I do? Help me, please

Hi Xiomara

How are you?I hope you are fine :) .I'm writing that because I'm don't know what can I do and I think that you can help me, all my problem started when I went a party with my best friend and in this party I met a girl she was the girl I told you I did not get along because we had problems in the past I decided to ignore her after she said she wanted to talk to me and I said okay no problem when we talk she said she wanted to be one of my friends and not my enemy and I told him I would think because so many things had happened in the past, she said okay. I don't know how to answer her question, can you help me?? 

See ya

Tatiana :)
