Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. I sincerely do not agree with your theses. consanguinity cannot cause this type of mental issues but causes normally physical problems. In your friends case, if you do not like his attitude, desert him. If he really loves you, he should change himself and come back in search of you. Other wise, simply he is not suitable for you. Leave him and be happy. If you require more of my help in this aspect, Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe the needed psychotherapy techniques which should help you cure your condition further. Hope this answers your query. Available for further clarifications. Good luck.
