I didn't like it. He had too much baggage and acted irrationally most of the time. FMC was a bit of a pushover but did eventually stand up for herself. Also, an emotional affair is totally cheating. She did Chad dirty by doing that to him. I don't like how they made it "ok" a few days later. He was happy with her and was about to move in. She gave him a key to her apartment.
I think the age of the daughter was developmentally around 5. She did not act like a nine year old. She came off as much younger than she was. I think writing her as 5 or maybe even 6 would have made her behaviors seem more age appropriate. Admittedly, its been a while since I have been around 9 year olds. She was a good kid, which was nice.
