When I look back on my various disappearing acts, I still think they were what was best for me in those situations, though I'm pretty sure there are people who were upset by it. If any of them are reading this, I am sorry for the bullshit I left behind me. I wish it had been different, but man, shit gets crazy sometimes and you're left with a choice of handling it badly or handling it far worse.
As with everything else, there are different levels and circumstances. Very few things exist in a black/white dichotomy. Yes, sometimes people need to leave, and leave now. Yes, sometimes you need to cut people out of your life entirely. But things like this walk that blurry line. On the one hand, yes, it could be argued that people deserve to know he is at least alive and ok. Do they need his address or number if he doesn't want it shared? Hell no. That's almost never ok. Life is messy, and that is one of the things this comic has so brilliantly portrayed. Everything from the tragic death of Wily to the relationship between Michelle and Christo is shrouded in layers of circumstances, what-ifs, prior experience, and personal prejudices. It can be easy and convenient when things are neat and clean-cut. Rarely is it ever so. Can we ever make the completely "right" decision? Will it ever not hurt someone or leave someone feeling the worse for what we feel we need to do for our own well-being? Shit man, if I ever meet the person with those answers, I wouldn't know if I'd even want them.
My two cents
I can see where Peter is coming from. I once had a roommate who ghosted me, and screwed me over for my rent 1 week before it was due, and no time to find a new roommate to help cover it. I was furious. I don't blame Peter one bit.
Should he tell people where Patrick is living and give out his phone number/email address/address? No. But if Patrick has given Peter that info (which I highly doubt as they just reconnected 20 minutes ago) then really, Patrick should have waited for Peter to agree not to give it out before he gave it out (which I highly doubt that he did).
Is it crazy to think they both have the right to their sides? Patrick with his decision to disappear and Peter with his anger? The thing about life is not every situation has a a correct answer that makes everyone happy.
I kind of understand Patrick. Yeah, the thought that someone might wonder about you crosses your mind, but it also crosses your mind people is fed up wih your bullshit and you're afraid to tell them "I'm doing okay" because you don't really know how long it will last, and you're afraid to let them down once again.
