The range of emotions are insane. I had a horrible morning dealing with an issue with my late father's estate and for some reason felt the urge to kill my H (ya know, cause it's my H's fault my father didn't document things as he should have). I had to walk by the family court building to go to my appt. and I wanted to scream like a crazy person.
I wouldn't call him back. Sounds like temperature checking to me - if it's urgent he will leave a message.
