We talk about the importance of boundaries here, but IME, many spouses don't even accept the concept of boundaries, or even being able to listen to their spouse saying that something isn't working.
Agree. Too often, contemporary society sees healthy boundaries as "you're controlling." "Controlling" is a buzzword that just gets thrown around, without a lot of thought, and is WAY misunderstood, IMHO. In fact, I think most relationships need MORE control (including SELF-control) ... not less! But that's a topic for another day.
