I was going out with this guy who, I have to admit, was extremely hot. We got along so well, and everything seemed to work out. But after about a month and a half, he started acting weird. So, I asked him what was up. He told me that he wanted to go back to his ex. So, I told him that if it would mean his happiness, then he should go. Well, after about two weeks, he decided he missed me and wanted to come back. So, I let him because I thought that I loved him. But I came to find out that the ex he said he had wanted to be with was my sister! What a jerk! -- Autumn, 18
