At the beginning of Secondary School I have been hanging out with the same group of friends. There was one girl in particular that I had gotten on with more than the others. In around Year 11 she broke up with her boyfriend who also hanged out with us. Since they had broken up on bad terms they didn't want to speak to each other so all of us were left with a choice of who to hang out with. When I found that no one wanted to stay with her, I did as I was more close to her than her ex. And so for the rest of secondary school it was pretty much me and her with the odd people joining us every now and then. Even during sixth form, our circle got bigger but we were still close. And then after we left sixth form, she ignores me completely. Throughout the summer she ignored all my texts and emails. I asked my other friends about it and they said she didn't respond to theirs either. Last weekend I saw her on the way to Central London on the Underground. We talked for a while and I asked her if she had got my messages. She said she had been busy so she doesn't know. So I asked if she had my number to make sure and we checked each others phone to make sure. I told her I'll text her later this week, to which I did do. She hasn't responded and its been like 3 days. And so I have given up on her. If she wants to ignore me then so be it.
