I loved him,he walked out.

Move on with your life,(am sure he has done the same) no need crying over a spilled milk. Focus on what matters most"YOU". Do what you love,let your friends know that your single again and in the market,attend meetings and church gathering..go extra miles. Do not lock yourself indoor crying,feeling sorry or blaming yourself! The best advice I'd give you is pray to God before going into another relationship,..know this girlfriend,if a man is willing to let you go,he was never really with you,so he is not worth your tears.
