<human>: I used to talk to a girl who was two years younger than me. We used to talk every single day for at least a year and a half. I definitely liked her and I knew she liked me, but I didn't know what to do. Then one day she told me this: "Tell me you don't like me". I knew the answer she wanted was exactly what she asked for, but I didn't know which decision was better; to say I do like her or to say I don't like her. I decided to say that I didn't like her simply because I felt like what she wanted was more important than what I wanted. At this point, a year and a half after she asked me that question, I'm still thinking about it almost every night. I even got into a relationship with someone else after this happened. We don't really talk anymore and I don't know what to think. I'm always thinking about her or that topic almost every night, and I always answer back by saying "I don't like her, she's probably with someone else, get over it". It worked pretty well up until recently, for what reason I don't know. At this point I don't know what to do. I want to tell her about this, but at the same time my guy tells me I did the right thing about telling her no. Maybe this is just something I wanted to get off my chest to relieve stress, but I just don't know at this point. I know the obvious answer is to tell her, but after not having spoken to her for so long, i feel as though she would be uncomfortable talking about it again.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My gut tells me not to say anything to the girl, but after a year and a half, I have the urge to do otherwise.
