I'd still give him a chance, and send a reminder email.

I sometimes have to send reminder emails to L. It's not that she doesn't read my emails or want to reply. Sometimes she just forgets due to circumstances.

With T, she double booked my very first session with her and askes me to reschedule!!! I was pissed and upset. I called some of my supports, and they convinced me to give her another chance. I'm so glad I did. I think I worked with her for 4 years? (My memory sucks). Next to L, she's the best therapist I've had. I only left her because she went on maternity leave, but I still email her every month and she's told me she's there if I ever want to come back.

So that's why I say, give him a chance.
