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.

I used to body-shame my partner by saying something negative about her height, looks, etc. But then I realized that I wasn’t having fun with her, but instead at her cost and it started to impact her mental health. I immediately apologized to her and stopped.

Whenever she would do something that I didn't like, I would immediately go to a negative place. Over time I learnt to ask myself - What are other possibilities that may be more positive than what i am thinking? Assume she was trying to help. Asked myself the question - What’s another possibility?

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.

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.
