Happy is the man who finds a true friend, and far happier is he who finds that true friend in his wife
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.
Over time i realised that i was showing love in a way that i understood and wanted to receive. I thought "doing things" for her was the way, but she wanted "quality time" together. A small change there had a huge impact on our relationship
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.
Little gestures go a long way in a relationship. Bear hugs, a good bye kiss before leaving for work, bringing home a small gift, or snack, etc are seemingly small deeds but have a great positive impact on a relationship.
Most couples avoid having difficult conversations that are necessary to create a life together. Instead, they try to avoid these issues and hope they would work themselves out. However, the truth is that they can't be on the same page without consistent communication.
