Apologize early and often; admit that you were wrong (if you were) and take responsibility.  Tell him that you were wrong and that you won’t do it (whatever it was) again. And then don’t do that thing again. Don’t use the sorry-not-really-sorry line of “I’m sorry you got so upset.” It shifts the responsibility onto him and makes it sound as if you’re not sorry for your actions, you just wish he wouldn’t get mad about it. If he responds with a--potentially justified--angry text, apologize again. Continue apologizing if he comes at you with more angry responses. Simply say something like, “I’m sorry--I was wrong.” Just apologizing or trying to explain that your intentions were good won’t work.  Saying you’re sorry isn’t enough--you need to show you recognize the negative consequences your actions had on him and that you sincerely regret it.  If he feels like you genuinely understand why your actions made him mad, he’s more likely to feel validated and begin forgiving you. Even if you don’t necessarily think his feelings or reaction is justified, apologize anyway. If you want him to like you again, you want him to see you understand how he’s feeling. Even if you say you’re sorry, it won’t be enough to make him like you again if you then start saying things that will escalate the situation.  Don’t, for example, say anything about thinking his reactions were irrational or unjustified. It will make him feel like you aren’t really sorry and don’t really understand the situation--and he’ll go back to being mad.  Don’t bring up things he’s done to upset you in the past. Turning the conversation into a tit-for-tat about who did what to who isn’t going to diffuse the situation. It will only make it drag on longer and make him less likely to forgive you. Asking for his input on what you can do shows that you’re listening to him and genuinely want to know what would make things better from his perspective. For example, you might say something like, “I know you had to wait 45 minutes for me and that it probably felt like I...
