I'm going to suddenly ghost a close friend of 3 years.
Why are you going to ghost a close friend?
I've been seeing her a lot recently, and she's just been texting me too much.
Ghosting someone, especially a close friend, is extremely rude and inconsiderate. You should at least have the courtesy to explain to your friend why you won't be talking to them anymore.
I'm going to just never talk to her again.
I don't think that's very nice. You ought to tell her why so that she doesn't have to worry forever.
