Complement her

You have to approach her as you like everything about her. Complement her when you see something lovely about her. Admire her beautiful smile. Admire her new dress or hairstyle. Tell her whatever you like about her. Do not complain about her habits and do not order to change her. If there is indeed a problem, try to discuss with her to find the solution. Show your liking for her visibly. Do not feel tentative. Hold her hand while walking. Put your hand around her shoulders which will make her feel that you actually care for her. Also, tell her that she makes you crazy, and that she's the sweetest girl you've ever seen. Tell her that she is the best. Compliment her on her beauty, also on her accomplishments, abilities. If she's a good snooker player, tell her she is smart. Make her feel that she is the best in whatever she does and this will build self confidence in her also about the relationship.
