You don't want to chat, just let us know instead of ignoring messages!
Don't tell me you appreciate the friendship and you want to be friends and then after a while just cut things off suddenly without explanation when we've been friends for so long!
Don't pretend to be busy when you're clearly active on social media! I don't know if they assume we're stupid or something I don't know...
I also think one word answers are not nice! Especially if the person cares enough to ask about you! You should at least return the question. I think it's way less rude to just be honest that you want things to end (i.e the friendship, the relationship or whatever) than to just ignore the person suddenly like they don't exist.
Be nice and please
I'm sorry, but I'm just VERY hurt by a girl who did exactly that... I know that some girls are not confrontational, but I think they should bother to do some explanation at least out of respect!
