maybe your friend doesn't agree with your what you are about to embark on and is afraid and apprehensive for you?
I have a friend right now who is embarking on something that I think is just an avoidance of her really life struggle (we all have one). I have told her this, but can't help sometimes being sarcastic and a bit rude to her as I totally am afraid and apprehensive about losing her friendship because I disagree and because she is moving away.
perhaps this it similar.
Anyone want to be friends on Facebook?
