Yes.
Whenever my best friend, who lives 3 hours away, talks about herself, I get sick. I want to hear what she has to say, but I can never make it through a conversation without puking.is there something wrong with me or the relationship?
You.
You definitely should move on.
But you won't till you hurt her by telling her you gag and puke when talking to her. Then you'll apologize, you'll have accomplish your mission to hurt her and then you'll move on.
Move on you're not her friend.
