There's this guy who texted his friend and his friend is dateing my friend so she asked my other friend and my other friend asked me if I liked this guy. I said no but on the inside I didn't really know if I liked him or not. But then on Monday I went to school and asked this guys friend if he really actually did like me because he said he did. His friend said quote; "No he is just desperate." That made me really hate this guy because he lied. Should I say something? Or should I just let it be and continue hateing him?

Jr High or grade school ? You said no, so of course he would say he was not serious so that he did not appear hurt or disgraced. These are called playing games

Jr High. And IDK. I guess because his friend told me that he has liked me ever since he moved to my school which was from fourth grade until now; 6th grade. So that would be 3 years; all of fourth, all of fifth, and so far sixth.

Hating is not healthy. Talk to him if you can't help hating him. You could also just let it be and continue on achieving your short-term and long-term goals in your life. Don't waste your time on hating anyone.

Thanks. I'm just going to ignore this and live my life. I'm not going to let him ruin my life I'm living and add drama to it.
