I am so sorry, it looks as though his family has frightened him off. It sounds as though you have made him your whole life, pinning all your hopes for the future on him. How did you keep busy before you met him? You need to try and find other activities to keep your mind off the situation, plan treats for yourself, take an interest in your friends' lives. Either he will eventually sort things out and come and find you, or he will decide all the angst isn't worth it and move on. There is nothing you can do to affect his decision, and certainly sending frequent texts will only make you seem needy, so try to hold off and give him the space you know he needs.
Your life wasn't hell before you met him, try to build it back without him, and then if he returns you will be a much more interesting person for him. You really do have all my sympathy, but you did ask for help?
