I read the article When Talking is Not Enough. It briefly discusses the importance of having boundaries within a relationship. I think one key phrase is "When we lower our expectations of our partner, they will act accordingly." I personally have found this out the hard way, like I'm sure many others have. This article mentions examples of a unequal marriage and parenting roles/duties, but it doesn't even have to be specifically about a couple. Boundaries are very important in relationships with parents, children, siblings, friends, etc. I likes that it told examples of what boundaries are and what they are not. I think many people do not know the subtle differences. While this article is very short, I think many couples would benefit from this, especially if they read it multiple times over a few days or weeks, so they are able to pick out different parts of the article to focus on and gain a deeper understanding of it.
