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 tried hobby swapping and found a whole new world of things to do together. Who knew? Turns out I actually liked some of his hobbies! Now we have a whole list of shared interests, and our bond is stronger than ever!
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
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.
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.
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.
