Before speaking with my partner about what's bothering me, I usually let him know what I hope to get from the conversation. e.g "I just want to be heard", or, "I want your inputs on something and love for us to problem solve together", etc.

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.

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.

Don’t complain about every small thing that irritates you. Be more accepting and let things be. Your partner is a different human being, so let them be that. Accepting the differences makes the similarities more enjoyable
