Five Finger Death Punch - Walk Away Lyrics Meaning

to me it sounds a lot like the last meaning, minus the relationship part. what im saying is it sounds like a guy/ girl likes another guy/girl and never gets a chance with him or her and has to sit by the rest of their life and watch him or her become swept away by their lover and never gets the chance at love. you could just call it window shopping, except you are wanting an admirer but not getting it. relationship problems to put it short.
