What if the man did wrong in your opinion, and not going to apologize. First, sit down and discuss. Perhaps your partner just did not understand what did he do and what offended you. Tell him your feelings, explain what specifically upset you. A loving man will ask me, even just to the second half did not suffer.
If a man never apologized, then he realized his guilt. This is a more serious problem, and here you need not just point out errors, and to clarify why your favorite is your wrong believes and takes everything for granted. For example, he went to meet up with friends without telling you about it. Perhaps in previous relationships or in the family partner was adopted with complete freedom of action. And he suffered this algorithm on your pair. Your task is to convince my beloved that it will inform you about your location, there is nothing that restricts his freedom. Tell me what you need it just to not worry about it. Most likely, one conversation will not end. So every time when the beloved forgets to call you, gently remind him about your request. Eventually he will get used to a new relationship and begin to get their only pleasure. And be sure to ask forgiveness if you break the promise.
Not only the acceptance of his guilt, but the fear of punishment causes the man to avoid excuses. In his opinion - sorry - so guilty. Innocent then punish. Encourage your man to punish him no one is going. Tell us what thing he did in the past and change anything. And his apology you only need to understand that he realizes the gravity of his misconduct and in the future I will try not to do it.
Do not start a serious conversation right after you found out about the wrongdoing of a loved one. Wait a while, at least an hour and a half. This break will give you the opportunity to calm down, to decide how serious the problem is and how best to build a dialogue.
