Boundaries don't require an announcement, just enforcement.

Dear Prudence,

I’m considering writing my family off (siblings—my parents are dead, and I love my husband and kids so not them!) but I’m really struggling with it. Here’s the story: I have many siblings and we’ve always been very close. We struggled as kids and had a very traumatic childhood. Both of my parents are dead so it’s just us. So we have bonded and I’ve always felt like they were the only people that understood me. We have the same humor, same interests, etc. BUT, they are all addicts. What was once seemingly OK-ish drinking habits have become stealing, breaking bones, domestic violence, lying, psychiatric hospitals, and terrible, horrible behavior. And it’s not only booze. It’s out of control and it’s all of them. I’m tired of being lied to. I’m tired of listening to why I’m horrible. I’m tired of the phone calls from jail and the women being subject to abuse most of all. Can I just walk away? Can I tell them until they are clean for a year I won’t be planning celebrations nor will they be invited into my home? I’m heartsick about what to do and I’m terrible with boundaries. I need to know what to say and if it’s even appropriate to not speak to them for some time. I’m just so stressed about it and it has taken a toll on my own family.

—No Good at Boundaries

Just stop inviting them. Stop taking the calls from jail. Just stop. You don’t need to tell them or warn them just be done. If they get clean and come to make amends you can decide then if you’re open to any kind of relationship at that time

You're not obligated to sit in the insanity with them. Boundaries are hard, but it will create a more peaceful life for you. If they ever get clean and try to make amends, you can decide if you're open to that, but you don't have to live like this.

I don't understand why people think they need to waste air on telling people their boundaries, and especially people who will take the long way to avoid respecting them.  No, nope, nein, nada, hell-to-the-no, are all full sentences that don't require additional caveats.  Don't answer the phone, respond to the text, lock the doors, turn away the carrier pigeon, FFS. 

TL;DR, LW yes, you CAN walk away.  It sounds like you should.
