Is it ok to feel this way about my girlfriend?

I absolutely love my girlfriend. I cherish her and would protect her at any cost. I always make her feel special and wanted when she is around me and i wouldnt trade her away for anyone else in the world. I always think about her and hope that she is ok and enjoying her life. I sometimes think that i am too lucky tomhave such a wonderful person like her. Is it ok to feel this way about her, if so, hiw do you think she would react if i told her all of these things? She already knows that i love her, and she loves me back, she just doesnt know about all of the other details i included. Girls, if your boyfriend told you he felt this way about you, and treated you the same way that i treat my girlfriend, how would you feel?
