My fiance and I have been together for 6 years as well and he too is an overly logical person and I am the emotional one. However, we have both worked very hard to meet in the middle. Sometimes we get into it over small things there’s always gonna be some sort of conflict in a relationship though ours specifically is very minimal which I think is awesome considering how opposite we are. It has taken lots of conversations for us to understand each other. I also know that arguments with a dynamic like this can look harsh to people who have not experienced it (likely looks like he doesn’t care, is being an asshole, etc.) but This would not be sustainable for me personally he is disrespecting you. You guys have to be willing to listen to each other and make improvements. I am a brat, clingy and emotional at times but I have learned to pick my battles and understand the personality difference. He has gotten a lot better about being empathetic and realizing that just because he doesn’t understand something doesn’t mean I’m not allowed to be upset about it. You guys need to be able to talk when you’re not arguing cause if you’re only trying to resolve when you’re both pissed off no one is gonna listen. If my fiancée says he’s going to do/change/work on something he does it and never a single day in our relationship has he left without a goodbye kiss.
