It can take a long time for the heart to heal and I know how hard it must be for you. You gave him your virginity and to you, that is like giving him everything. I know it feels like you have no more love to give someone else, but once you get back on your feet and begin to live again, you will find that love is boundless. You always have more love to give. First though, you need to heal from the hurt this man has done to you. Cry, scream, mourn his loss, but then you need to begin to live again. Fill your time with activities. Try not to spend time alone. Get rid of pictures, clothing or gifts that remind you of him. Say goodbye to him in your heart. This isn't going to get better over night, but it will get better in time if you try to keep moving. Get up each day. Run errands or go to school or go to your job, but keep yourself moving.
I wish you nothing but the best and I am truly sorry you are going through this pain. It will get better in time. I promise. Just hang in there.
