I emailed the exchange to xgrpcoT, and she responded that it would have been good if he offered me some options or ask the new person to wait a week. That there are so many options and possibilities to be kind to everyone. She reiterated my idea that perhaps a new person can witness someone leaving appropriately.

She agreed with me that it feels like an F-U and that it sux that I don't have his support. She also said that she doesn't know if he realizes how cold he sounds.
