Normalize not staying connected just because you're related or have known each other forever. Don't stay just because they'll feel bad, you're choosing distance for a reason. And don't feel guilty, they knew exactly what they were doing all along. They knew before you did, because they did it, repeatedly, comfortably, without hesitation. And probably planned to keep doing it, just counting on you to keep tolerating it. So of course they're upset now, your boundaries came in unannounced and ruined their pattern. But that's not your problem, that's the cost of actions finally meeting consequences. It's almost funny, grown adults acting shocked like disrespect deserves flowers instead of distance. Like... did they expect a thank you note too, or just a standing ovation for audacity? They should've thought about it while taking advantage of your helping nature and giving habit so casually. But thinking ahead clearly wasn't part of their skill set, only taking was.
