How do I help my wife's self esteem?

Sorry I meant Self Esteem. By the way I am on my daughter's yahoo awnsers. Okay so my problem is I am muslim and so is my wife, and I know in the Quran that I am obligated to please her which I try to do. I kiss, i complement her, I hold her at night when she cries. My wife is so special to me but she is not special to herself. How can I help? What do I do? And another question: I think I am to playfull with my wife. Imean I chase her around the house, i sneak up on her and grab her from behind just to kiss her. I throw things at like pillows and stuff and laugh, Imean I know i am silly but is this over the top. Thanks for all your help and advice...
