Parts of you life reminded me so much of my own past. All I can say to you is you are strong and having been through what you have been. You can be strong again and over come this. I know its hard. I don't think he doesnt love you anymore its just that people grow away from each other at leas he had told you instead of stringing you along. At his age like most guys want to date rather than be in a serious relationship. Please keep strong you have been through much worse.
