She is older than me two year, But I love, How can I do?

You need to talk to her and express your feelings, otherwise she will not know how you feel. Have you talked to her about possible having a relationship before?

I think she knows that you like her. Girls always knows. If and i said again if she has the same feeling as you, i don't think that she will say it first. You have to be man enough to say the words. I am happy for you if it works but i am sorry if it's not. I am sure she will not hate you if you try.

How can you forget her or how can do what?
