Yes, past and memories bothers you sometimes I agree. But once for a while you have to forget it and move on.
You know why??? Just for your beautiful present, yourself, your beloved one who is dieing for you and your love.....
Because the thing which is gone has nothing for you but the thing which is with you right, You are life of that person. Their reason of breathing, loving, feeling, smiling and living. Nothing can be enough for that person except you.
So be with them not for future because no one knows it but for present because no one knows and loves you better than them
