Julie Is Ghosting Chris, Was It Something He Said About Her Daughter?

Chris calls us to see if we can connect with Julie. They met at a networking event in SF recently and really hit it off! Lots of texting and funny banter and they FINALLY had dinner a couple weeks ago. Everything was going so smoothly (and he rarely dates so this is a big deal for him) and in the middle of dinner she said she "wasn't feeling well" and left abruptly. He followed up that night on text....no word back. Was it something he said about her daughter?
