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.
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.
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.
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.
Understanding where my hurt or fear or neediness came from was the first step in helping me strengthen our relationship. Getting to know myself better really helped me feel happier in our relationship, including the hopefully passionate, exciting, challenging, and rewarding life-long relationship with myself and my partner.
