“Family Conflict and Distance in Islam”

I don't know where to begin in my life. I'll keep this restricted to family relationship. My family relationships have gotten so strained that I have chosen silence and separation. I can provide so much information like I have in the past to my family, they don't care. What consistently make excuses for them. Others tell me. I witness the neglect but I ignore. My mother is not an educated woman and my father did not have a father. They are also old. I have always kept a warm and kind heart towards my elders, my biological and adopted family. Even meeting with my mothers brother who sexual abused me as a child, scare I am suffering til today. Psychology they claim that I am disturbed. I went to the psychiatric. Psychologist says my family is neglectful. Because of the sophisticated education needed to understand psychology, I abstain and bring it back to Islam. My family are not educated scholars but they have run out of bullets to hurt me, so they turn psychology and in Pakistan, everyone is an expert at finding flaws in others rather than fixing yourself and be mindful of my own behavior as it taught in the untied state of America. Are my actions of abstaining and distant and silence acceptable in Islam? It truly breaks my heart, but I can tell you fact for fact, date for date things that have brought me to the juncture. I will always respect my biological family but I am a math and science, introvert (in certain aspects), while they enjoy gossiping, fighting and more Culturally this is acceptable in Pakistan. However America has no religion. One must renew ones faith as needed. So I try to judge my actions based on no violence and Islam. At heart I am a business man. After 15 years of this cycle I am writing this letter on hopes of getting closure. Please feel free to ask me any questions but I am fasting at the moment. I can tell you in heart I want justice and vengeance but I break my heart and attempt to follow Islam. Second, I am forty years old and not married. I am in such a bad part of my life right now, that I am scared of bring another person, my wife, into my life. I would like to resolve these issues first before moving forward. Is it wise to delay marriage at my age if I am dealing with consequential outcomes that could affect my wife and future kids?
