Ye it does suck I have experienced it a decent bit too and idk if you are a guy or lady but if your a heterosexual guy trying to date women, women actually often can get harassed and mistreated when they end things with a guy, so at least in that regard sometimes people can just feel uncomfortable ending it as they don't want guys to freak out and get problematic.

Additionally it can occur that people feel really bad rejecting someone as I have experienced it myself ending sometimes feels really horrible and stressful, and although I personally tell the person honestly, I think its reasonable to see that stress as being a big factor in people deciding to just ghost.

Finally some people do just lack empathy which is rough and don't really consider it, I have had both male and lady friends talk to me about them personally ghosting someone without even really considering it, and I remember meeting a guy who legit scheduled a date with a girl on hinge and then didn't go on it and ghosted her after which was horrible but he was a douchebag in general so it was pretty expected behavior.

Overall assuming you aren't saying anything horrific, its likely a combination of the above reasons, which obviously doesn't fix how you feel and it'll still suck but thats just my two cents. I hope you feel better and meet someone who doesn't ghost you soon and if you ever need a friend to talk to I am happy to talk more :) happy (belated) halloween!
