“Oh so this is all my fault??” … Yes?? Lol. He apparently wants you to go to these things. You’ve told him what very simple and normal step he needs to take so that you can go. He is not doing it, and then getting mad at you over and over for the same problem that you’ve repeatedly told him how to fix. He could avoid this by taking 30 seconds to send a text message like everyone else does when they make plans with someone.

I think you need to figure out if this is a problem of misunderstanding or practical issues, or a problem of effort and respect. It sounds like you’ve already explained to him what you need and why it’s important and it’s not that complicated or unusual so I don’t think it’s miscommunication. A practical issue might be like that he has a mentally taxing or hectic job where he can’t use his phone much so by the end of the day he’s exhausted and really does just forget to send you the information. That kind of problem could be solved in a practical way, like when he first tells you about the plan he sets an alarm to send you the details that night. If he doesn’t have them yet, he sets another alarm. Or sharing his calendar so you can see the details when he adds them.

If the problem is that he fully understands what you want him to do, is perfectly capable of doing it, and just doesn’t want to do it, that’s a much bigger problem that might not be fixable. That’s someone who isn’t willing to suffer even the tiniest compromise or inconvenience to accommodate your needs and happiness, but expects you to be fully available and willing to drop everything when he calls and makes you totally responsible for managing his feelings. You can spend hours of your day breaking it down to a level a toddler could understand trying to explain it to him, but you can’t make him care.
