Well see you need to give yourself time. It must have been hard on you buddy but then you need to move on in life as it waits for no one. Probably go on a solo trip to get over things
I know it gets difficult at times to accept but, We cannot make someone feel the same way we do.
Try to accept it and appreciate your courage that you actually expressed how you felt.
its very important to let go :) try on someone else, a second chance is always worth it. love is very different from attraction. love takes time to develop. so may be you wil find another partner with whom you will have all those beautifull experiences that a person who is in love experiences. its a systematic pricess to fall in love. so convince your mind to let go of her thoughts, memories and imagination tooo.
