Definitely sounds like there are some things to get settled! (BTW I always wondered how you handled that party situation!) I was double-booked on like my 2nd session, got a call and rescheduled, but at that point it didn't bother me. Only other cancellations were due to deep snow or a power failure at the building. A real work-a-holic, never a sick day.

You have to ask your questions....

• Canceling bothered you, will it happen often? You may want to pick a different time when he's less likely to cancel OR another therapist with a consistent schedule?
• How to reach you - did he just know the format of email addresses for the firm since his wife works there, how did he get that since you didn't give it to him?
• Getting a call - is there a way to reach you, even if it means you might not get the message until it's too late?
• Has he told his wife about you? (no he should not have, and he should NEVER).
