Life is short, and we don't have forever to wait for someone or to play the blame game. If you know you give your all in the relationship, and that person did nothing but walk all over you, forget them and move on. While you're sitting there crying, and losing your hair and sanity over this person, they are out living their life. Look at it this way, should you pay for something they did? HELL NO!! Before they entered your life, what did you love to do? Did you write poems, read books, dance or just hang out with friends? Whatever it was, try going back to what used to make you happy, and use this break up as lesson and never let someone bring you to your keens again.
