There are people I choose to be around/keep in my life that cross my boundaries pretty durn consistently.
It’s not reeeeeeeally a problem (yes, yes it is, it’s annoying as f*ck), because boundaries are what I DO, not a way to make them change.
That little back&forth up there between me & myself? You’ll note it’s …annoying… rather than any of the bada BIG bada BOOM reactions. Because my boundaries are scaled back enough that I’m exiting / regrouping / whatever whilst they’re still waaaaaaay back in soft-limit territory. Where I’m leaving the room & rolling my eyes, or hanging up the phone, or going home, or whatever… they’re just them, being themselves… looooooooong before we get to hard-limit territory & I’m ending the relationship / removing them from my life, entirely.
If you want someone to change? That’s not about you & your boundaries. Or anyone else crossing them.
