although it is hurting, maybe you should be thankful that you found out earlier that he is not the one rather than later because once you are married and with kids, things are much more complicated. do not close your heart. let the pain in and feel it to let it pass. because if you close it, you will also close it to the good because the heart cannnot distinguish, unfortunately. i know this because it is what i do, when i close my heart to the bad i also close it to the good. it is impossible to live life without getting hurt. we can only make better choices along the way.
