Isn't that the same as, "It's not you, it's me."? But really, they're both lame-ass kiss-offs. "I need space" more than likely means, "I've already found a space I want to occupy and it's with someone else." Jaded? Moi?
yep it's kinda like - I need to talk to you, but I gotta go right now. Later!
none of these ever bother me anymore - I am impervious to everything like these and more
It never bothers me when you ask someone something, they hear you, but they just don't answer, nothing, nada not even a shake of the head! They may just sit and stare at you like "I can't believe you're asking me that!"
Or, "You aren't very good at communicating, are you?" when they were the one who refused to talk about it!
but I will not bore you with more - I could go on - but I won't.
