8 diff??? go for it she ain't no baby, may be she knows more than you think about your feelings... go for it gently, if she says Yes throw us a party, if she says No two things are possible, either she'll think over it if she has never thought about this relation and may get attracted after knowing your side, or her No may mean actual No, but in any case, you will be satisfied that you did what u could. Otherwise u'd be wondering for ur whole life...what if... what if i had asked her....
