Cut them off
If they stop communicating with me and I can tell I'm being ghosted, I will send a final message letting them know that ghosting is immature and cruel, and that I hope they can do better in the future. Give them a day to respond (they probably won't) and after 8 hours max after sending that final message, block them on every channel that I have their contact on. Then, delete their number and every message they've ever sent, unmatch everywhere - I do not give myself any chance to make contact with them again, no drunken texts because every trace has been deleted and there is no way to contact. But more importantly I don't give them a chance to come back in to my life and do it all again so block block block. It's helped me recover from ghosting episodes and it's what they deserve, to be completely cut off forever. Oh also never add them on socials in the first place. Love, a Scorpio x
