It may seem very obvious but this seems to be one of the things that people forget to do during an argument. You need to be willing to hear what the other person has to say. You can not disregard what they are trying to convey. What good is that going to do in the grand scheme of things? You didn’t listen before? Now that same issue is going to come back in a couple weeks and you’re back in this vicious circle of arguing about the same issue over time. I’m willing to bet that if you listen to the issue the first time it will not be an issue a second time.
