If a boy likes you and you don't like him?

I am in the same situation right now. A boy has asked me out but I'm not sure I feel the same way as him. My advice is:

• Try going on a date with him. Just 1, and if things don't work out just tell him that you don't feel the same way towards him
• Just tell him that you are not interested
• Tell him/her that you're bi ;)
