ok so i told my friend the guy i liked and then she told him and it made me so mad but the thing is that when she told him he said that he already knew but the only people who knew was me and my two friends but they swore they hadn't said anything before and then before he liked me but i wasn't allowed to hve a bf then so i didn't say anything and i think he still likes me so i am not sure but he still acts like he likes me because every time i look at him he smiles back at me or he is already staring at me so i am truly confused! please help! should i talk to him or should i wait for him to say something first?
