Betrayal

It has been a few weeks since my boyfriend had broken up with me. He went back to his ex. What hurts the most is knowing that he was going out with me while he was also with his ex. He only used me. I feel shattered. I wish I hadn't fallen in love with him. I loved him with all my heart. He was the one I lost my virginity to. Forgetting him and moving on seems soo difficult. :'(
