hi thanks for query, I know beings close to some one for few time, later if they separate its bit hurting. but don't you feel that every body has there own space and things to follow. some time they want to independently with their own thought process. did you try to speak with him regarding your situation/ feelings. do you aware the reason for possessiveness. is that you feel lonely/ scared because there are no body to share your emotions. you can meet any psychologist in your place, they will help you to handle the situation and get clarity of self. take care.
