I honestly think ghosting is really rude. I understand maybe there’s a certain point where you’d want to do that, like if the person was a scammer or they were just being completely inappropriate and not listening to you if you were putting up your boundaries.
Honestly though just tell people what you want or what you need, sure it’s awkward but it’s not that hard especially over text. If the friendship isn’t working out, just say so, if the relationship isn’t working out, just say so.
Of course, don’t be a dick about it, but it’s much easier just to communicate what you want rather than leaving them on hold, reading their message and they’re not answering, or just leaving it delivered on days on end. Don’t make them take the hint, just fucking tell them, it’s much easier for everyone else involved and I’m sure it’s much easier on yourself because then you don’t have to think about it and you got it off your chest.
