<human>: Can you give me the gist of the text in a nutshell?

My girlfriend says that I'm not trying anymore and that she doesn't want me to tell her the same stuff over and over. She means the way I describe how beautiful she is and how I love her. She has a low self esteem and constantly questions it, so I'm constantly telling her. Know she fells like I'm not trying as hard as her in this relationship. She is always asking me if she is the only one that I love and that if she is the only I think about. 

Of course I say yes because I truly love her and she loves me. She has told me that she always brings it up because she loves me and wants me to do the same. I do try, I have gone into specific detail on how beautiful she is and how much I love her. She says that that's not enough and to put more effort into saying it differently, but I have I constantly find new ways. She still says their the same. What should I do, how should I change what I tell her, how can what I say to her have more meaning. She says that what I've said already has lost meaning because I say it all the time. I really do love her and want her to feel important and special, that's what I've been trying to do the whole time.
<bot>: my girlfriend says what I say to her is getting meaningless and wants me to keep on rephrasing it and make it sound different.
