how to deal with getting ghosted?

i don’t understand how people just ghost knowing the other person is literally getting anxious and over thinking. and no i’m not talking about strangers ghosting you because that’s still easy to move on from, i’m talking about people you know irl. i’ve been dealing with this recently and it’s getting to me, thinking and rereading conversations just to get a hint if i said smth wrong but can’t really figure out what :(
