There is one girl I like and I don't know how to tell her that, I have a feeling she knows but if she doesn't I don't want to make a fool out of myself how is one way to boost my confidence on asking her out
Talk to her as you would normally. Be friendly with her and be there for her so she can trust you and also get to know you. As your friendship gets closer, you will be able to confront your feelings easier.
