25-that's an old narcissist trick. The "mistaken" email. Quoting a part here from a list of favorite narcissistic hoovers:

Text messages that are supposedly meant for someone else, but sent to you by mistake: “See you in ten minutes xoxo” (Supposedly for his current girlfriend–sent to upset you.) “The boss just moved the meeting to Wednesday at 3pm.” (Supposedly for his coworker–sent so you feel a sense of obligation for the coworker.) Or, “Sam called and said John is in the hospital and to call him immediately.” (Supposedly sent to someone else, but sent to you so you feel a sense of urgency to get back to him.)
