There are two types of apologies: those where you feel you have to say sorry to diffuse a situation or just move past something, even if you aren’t sorry, and those where you feel genuine regret and want to make a heartfelt apology. In a relationship it should always be the latter. If there is no regret, don’t say sorry. Deal with the situation, compromise, but don’t say sorry if you’re not. And when you are sorry, say it with conviction.
