What to say when someone tells you they love you but you don't feel the same way?

First, put yourself in their shoes. Rejection hurts no matter how nicely it's dished up. Find a way to say you care. For example, you could say something like "I really love spending time with you, but I feel you're moving a little too fast for me".

I would touch their hand look at them in the eyes and say "Look you are an awesome friend and i really like you but I'm just not ready to love you i don't feel the same way I'm sorry i do still really want to be your friend and maybe someday we can be together."
