What is wrong with this girl?

shes just in love, the difference is that you might love her one way and she loves you in another way(meaning she loves you more). tell her that your past relationships were too emotional and that you need sometime too think because you really love her but you dont want to over load her with love. she might hate you for a week or two. but if "loves" you, she will understand. if not she was just obsessed with you...
