Help me choose who should I have a crush on?

Only you cant tell which one you are truly interested in more. I cant chose who you should like but can only reflect on what you have told me, however I don't exactly see the significance of your dreams. You seam most attracted to girl three since you always have a good time with her. The first girl might be ideal since you respect her values and have known her the longest, showing that you are compatible. Your most intimate with girl two which is vital in relationships, but her lack of maturity will continue to bother you if it does now. Hope this helps your decision!
