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.
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
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.
Having shared goals and working towards them together has been very helpful in keeping our relationship strong e.g saving for a vacation. Having something to work towards together keeps us motivated and gives us a sense of accomplishment.
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
