Just when i thought i moved on,, wht should i do?

About a year ago we stopped contact for good.. Back then He knew i adore but he lost interest in me obviosly and had a girlfriend and refused to have that day u met other guys, well as i thought started to have feelings for ano m trying to convince myself that i can love others than the first one... But w im trying to convince myself that i can love others than the first one... But w saw him in a party after one year of the day i fought with him.. I had those again,, "why i loved him not someone else",,, the way he smiles, the way he move, looks, the way he thinks and express himself,, how shy he can b som but cover it up with a cold look.. I adore him.. I couldnt stop myself from st someone just like him,, i know hes a good hearted person although he is hu i c him from now on,,.. I want to forget him but i love him,, :(
