My partner would sometimes  react strongly to a situation and it would catch me off guard. Over time we learnt to talk about it once things calmed down and it helped me better understand her triggers and how i can avoid them.

When we fight, one of us tries to stay calm and not make it a win-loss ego situation. It doesn't mean don't share your point of view, instead, wait for the nerves to have calmed down.

We realised that division of household chores makes everyone better off. Over time we figured out what each one of us is good at, what we each love/hate doing, and then arranged accordingly.

I realised over time that not all conversations are meant to be discussed logically, some are purely emotional e.g my partner feeling jealous when i speak with a girl is an emotion and I shouldn't try to explain it logically. This change made things so much easier for me.

You know that saying, "All work and no play makes Jack a dull boy"? It's true for relationships too. If you're just going to run errands, discuss chores, and then zone out in front of the television for "fun," you're missing a whole level of connection.
