I'm going to ghost my friend of over 2 years
Why would you ghost them after such a long time?
I don't know, we have just grown apart.
that is not a nice thing to do. It is wrong to end a friendship without reason. You should really try and talk to your friend instead of ignoring them.
Why would I want do that? I will just get bored of them again.
Don't you think you might end up missing your friend? You have been friends with them for a long time. Maybe you should rethink ghosting them just because you are bored with the relationship currently.
