Okay…and how is that different to resenting that he reacts differently? You react one way to him “offloading” to you, you sit through it as you think it’s fine, he reacts differently because you speaking to him angrily upsets him/makes him feel angry, hence the “drama”. Therefore, you resent the fact that you are okay with it, but he isn’t when the roles are reversed.
Again, as you’ve been told, you can’t control his reactions to things. It’s VERY normal
to not like someone “angrily” speaking to you.
Communication is very normal in a relationship, yes. EFFECTIVE communication is incredibly important in a relationship. But using your partner to offload your anger about a situation, (which is exactly what you’ve done, read your own first post- you were angry and told your partner angrily), is not normal, and not healthy.
It’s not really about the wifi specifically, it’s about going to your partner angry and then speaking to him ANGRILY (your words) about anything. What would make me unhappy is my partner speaking to me ANGRILY about anything, as an adult you should absolutely be capable of communicating with your partner without that anger. There’s absolutely no need for it as an adult with your own mind, there were plenty of ways to communicate that in a healthy and effective way, without upsetting anyone, if you just take the anger out of it. You were angry, you spoke to him angrily, it’s not something he caused or created, NOBODY likes being spoken to “angrily”.
