Search Results: he stares at me and then ignores me

I'm sorry most of u are sick of reading about this. But a guy liked me and I did. However, he thought that I liked another guy so he acted as he love another girl and I ignored the other guy , thinking that he will ignore her as well. Unfortunately, he kept going and he broke my heart many times although he was in love with me. I showed him my love to him many times and every time I did he seemed very happy. But at the end I gave up and I decided to do the same thing to him and I acted as I like another guy and I kept going and he was very jealous, like a lot. But one day I had to sit near him but then he moved and he started to throw things at the other girl and she started to stare at him ( coz she likes him even though she is in a relationship with someone else) and he stared at her. However, the next day she stared at him and as he sits near me I heard him saying ( what u looking at?) . And it was the last few days in college so he actually started to talk to me a bit like trying to do things to make me talk to him but in a friendly way and I did something kind to him and he said thank u brudda. Also every time I went on my phone in lessons he did that as well straight after me. But now the college is over and he didn't even add me on any of my social medias also didn't even talk to me last day I saw him.
