I talk about boundaries often. I know a few other folks in the survivor community who also talk about them often. It’s not a coincidence. Learning about healthy boundaries and how to keep them is a vital part of healing.
It’s a vital part of living a healthy, adult life as well. Survivors don’t even do a good job defining what healing is, but this would be a good place to start.
Robert has a long post complete with references on his website. If boundaries are new to you, this is a good place to start. If boundaries are not new to you, it might be worth checking out too.
