There is a boy who first tell me that he loves me,and I also have feelings about him,but know when ever I see him he is ignoring me.Please tell me what I should do?

First of all, go to him and ask him why is he ignoring you because first he liked you and now he's ignoring you, so just ask him this and if he still says that he likes you then just tell him that even you like him a lot and if he says he doesn't like you anymore then I guess don't tell him that or do as you wish!
