sorry your day has begun so badly. I personally would be more than a "bit" freakie so maybe you're handling this better than you think.
The whole thing is a learning process for all involved. Give yourself time and allow yourself some mistakes. Do learn from your mistakes as best you can because the mistakes are painful and slow your healing.
Can you screen his calls? I know I would wonder if the call was something really important (maybe health related etc) and feel obliged to answer. If he leaves a chatty message, or no message at all, then you would know the call wasn't really important. Then YOU could decide to pick up or return his phone call IF you felt you WANTED TO.
Try to shrug this episode off as best you can. Just say to yourself, "Well, THAT was a mistake but I'll do better next time."
Hope the rest of your day is better.
