I'll try to keep this short, friend and I had a falling out, she lives in another country. Emails were exchanged, but she still hasn't taken responsibility for her part in the falling out, I sent the last email to which she did not respond to, so I left it. We haven't corresponded in over a month. She's back in the UK for Xmas (has been for a few weeks) yesterday I received an invite to a party she's hosting, would I be unreasonable to not go to the party or not even respond to the message i would feel uncomfortable that the air hasn't been cleared. I could respond saying this, but I think it might make the situation worse, but I feel that her choosing not to respond to my email then acting like nothing has happened by sending this invite is pissing me off. Am I being petty to expect we clear the air and move forward, rather than brushing things under the carpet and carrying on?
