Is it forbidden to not talk to my father for the rest of my life? I haven't seen or talked to him in 7 years and me and family are better off without him. He's unreliable and has shown no interest in any of ours life even when he was here. The first only reason him and my mother were even married was because it was arranged.
Sorry about your situation. Unfortunately that is forbidden. We are not allowed to cut ties with blood relatives, it is one of the major sins the Quran warns us against many times. You can try to be polite and dutiful even if you don’t have any good feelings toward him. You may be interested in this previous answer: Is it sinful in Islam to not love your parent?
