Somewhere along the line, my husband decided he was perfect and doesn't make mistakes. So he doesn't apologize either. Perfect people don't think they have to. This is quite a flaw. I have once or twice, with tremendous effort, gotten him to admit that he was wrong. I thought he would break saying it. I don't insist of apologies much because they are so hard to get. Most of the time, I can get a promise that he won't do that thing in the future. Then when he does it again, I can tell him he was wrong to do it!
