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.
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.
Giving time to yourself and your partner to adjust with each other's habits, patterns and personality is important for a relationship to grow. No magic happens in one month or few weeks; a relationship takes its own time to cultivate.
As a couple, staying friends has always been important for us, so we have a lot of simple rituals that help us stay that way. E.g together we write inspiring, funny, and uplifting messages on sticky notes and leave them in unexpected places around our community.
I unknowingly started expecting my partner to be a reflection of myself, often asking "why can't you also" when pointing out things I do. But I realized that he brings his own strengths to the relationship, and expecting him to mirror me is not fair or healthy.
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.
