I want to tell her I love her..?

I think you're smothering her a little bit. Stop telling her "I love you" That's what she needs. She needs for you Not say it anymore for a while. Sounds like you are clingy. She may be getting turned off with your co-dependency. Cut it out while you're ahead. It's nice to know that you're madly in love & I commend you for trying but give her some breathing room then you'll have her in the palm of your hands. Good luck.
