Even if you like someone a lot don’t give in to him and try to please him in any manner possible .When you try to please a guy early on he becomes relaxed because he knows he has already won you over.Even though you may like him don’t express your thoughts to him for several weeks.Date him but express your feelings only when you are sure he is completely in love with you .If you want a serious relationship you have to understand how to make a guy chase you.
