I actually never argue with my bf really, I don't think we have ever had an argument. We have differences of opinions on many things since we are like a yin and yang type of opposites in many ways but I think we really respect one another's differences and are able to discuss them without confrontation. If it is important we are happy to change for the other person too if it is a reasonable ask, I really admire that he is able to take on board things I say and not get offended but instead actually say I see your point and make the changes, thats not that easy to do because it's easy to get defensive when someone picks out something that isn't favourable about your actions. I have had quite a few toxic connections that pushed me to grow and evolve and learn how to be able to communicate with a partner without being triggered, so I don't think it's luck, I really think I earnt this more harmonious connection by working through so many intense connections and doing the work on myself to meet someone who has also done the work on themselves to be able to communicate instead of argue. Of course it takes two people, if the other was still argumentative it would take being a saint lol but I do think you attract what you are on most levels.
