I'd say go with "option 2", things happen and it was nice that he made the attempt to let you know the way he did.
I know from experience what it feels like, and it can leave one feeling hurt, but things happen.
The reverse can happen, the client's car can break down, a family crisis, and or T getting ill can occur, we are all human.

Now, if a T tells the patient, "I do not want to see you anymore", with or without an explanation why, can be a valid reason of feeling hurt,angry and/or frustrated.
One time my former T had to cut our session by a half hour, cause he had a client in crisis, was called by the parents and had to meet them at the hospital, so of course I couldn't be offended, that other person could of be me, and my T made up the lost time so I wasn't gyped.
Though it's hard, try to understand it wasn't intentional.
I wish you lots of luck with all of this.
Take care now,
