Talk to her

Do not be silent, talk to her about everything that comes to your mind. If she has feelings for you, she will be interested in it, and she will understand that you trust her. Tell her that you are pleased or worried. She will rejoice or worry with you. Search for the right literature. Reading is rather helpful in case if you do not talk it over with your psychologist. For instance, looking through site you may find a lot of helpful things.
