Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. You must use such words with care. Talking to self, walks in circles and doubting are not symptoms of psychotic. But they are of over thinking or being preoccupied. Your boy friend is preoccupied and he doubts you because of the preoccupation. You shall talk to him regarding this. Let him know that he is behaving in absurd ways. Awareness can cure relatively simple problems. If he is not interested in you and when he is doubtful in you and when you say that he is psychotic, then why do you want to continue the relationship? If you want to really help him, take him to a psychologist / counselor and he can help you professionally. In case you want my further assistance, Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe some psychotherapy techniques which should help you cure your condition further. Hope this answers your query. Available for further clarifications. Good luck.
