Hi there, in fact its quite common for a couple's relationship to turn from "passionate, romantic" to "normal, dull" after a few years. But how do you determine whether you still love her or is she important to you?
Imagine, right at the moment, she disappeared. She is no longer in your life, be it dead or whatever. How do you feel? Can you live without her? Will you feel extreme sadness. I believe you still love her if you think you can't live without her.
