Over time and after quite a few conflicts, I realized an important thing - I should keep the conversation focused on the issue at hand and not criticize my partner at the core of their character. That’s the difference between complaint and criticism.
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.
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.
One thing that has made us very secure in our relationship is truly accepting each other as we are and giving space to each other to be our authentic selves. Obviously, we don't like everything about each other, but accepting these differences without judgment is very important.
As you grow together, remember to keep doing the things you did the first year you were dating
Building open, clear and safe channels of communication in your relationship not only removes the stress and distance of guesswork, they also bring in fulfilment, empathy and a real chance of growth. Remember, no matter how well you know your partner, you can't read their mind.
