Demanding for something from a person into whose life you've not invested that very thing is abuse. Life is about investments. In marriage or family relationships, people tend to get angry and agitated at each other because of mistakes. These mistakes might be repetitive or annoyingly common. Well the best thing to do is to teach, train, guide and help your loved one in those areas of weakness or faults. When you do that, you'll be investing into their lives and your dividends will be pleasing. Make a point to invest what you desire into your spouse first before correcting or telling them off. If you do that, you'll have eliminated most marital conflicts.
