Dear LIB readers: I am about to marry a man I no longer love

From a female LIB reader

I am about to get married. My wedding is in fact 16 days from now. I just realized I dont love my man like I used to. I dont know how to tell him how I feel. I am so scared to break his heart. I have been trying to rekindle my feelings but its not working. I am so confused and don't know what to do. I know I can't cancel the wedding because everything is set but I can't help but feel I'm making a mistake. What should I do?
