Tell us about yourself!
I'm a girl so I thought I might be able to help. Start by complementing her. Don't make it awkward thought. Maybe next time you talk to her tell her that her hair is nice today or maybe complement her eyes. If she has insecurities complement her on them. Tell her that you see her as a great friend but also as more than a friend. Use her name a lot and look at her in the eyes. Show her you are confident but not pressuring her into a relationship.
