I don't think Will asking "is Hannibal in love with me" was a way of getting confirmation because he was scared of Hannibal deceiving him. Firstly, I don't think Will's scared of Hannibal in any capacity or form, and second, he would be capable enough to face Hannibal in any scheme he'd possibly plan. Will isn't stupid or blind in the way others have been blinded by both or either of them.
I think he needed the confirmation because knowing he is loved thoroughly for who he truly is, will never allow him to become a better man, and to acknowledge Hannibal's feelings is to acknowledge his own as well, which speaks volumes about the kind of man he is. And he has been trying to pretend he's anything but that man for a long while.
