Lot of us goof up and then to avoid wild consequences stick in a sorry..even though mostly it is not heartfelt. It is like a quick solution to a bigger problem. People who are married know what I am talking about. Are you serious about your apology? This is something for you to think about. I would say this is the anatomy of an apology.
What does that mean to you? If you really want to patch things up and get to the bottom of the problem (not being manipulative here!) , given above are the steps to do that. Strongly recommend..Missing any of the steps would lead you to do this process again until you get it right..
