You're pretty gullible. Someone who is dying from Covid doesn't hang on for so long. Long haulers are not in mortal peril most of the time, so you were involved with a serial exaggerator or an outright liar.

Maybe it was written poorly, like OP was talking to him for a year, then he began "Dying from Covid" recently to get rid of her. This shits so old to use as an excuse, I remember people using it in old Yahoo chatrooms. I'm surprised they didn't default to Cancer, but I suppose Covid could be much quicker. ¯\_(ツ)_/¯
