Sorry for double comments. I didn't really like not having much to give you as far as what I was thinking for her. I could possibly make her a teacher, maybe currently teaching his daughter. Other idea I had was that maybe she lost her house in a fire and his company was contracted to help do the rebuild? They built up a friendship during that, possibly have children that are the same age so they keep getting thrown together, which leads to the flirting. I'm still trying to nail down a PB so her details are still a little hazy for me, I have too many directions I can go in.
