Hello, I'm a new fan of C-novels. It's a modern C-novel. The main plot is the girl gets time traveled or was it reincarnated? I forgot but the main plot is Protag's husband is a cheater, She knows he will cheat on him on a girl that is "plain" from the bar i think. As the story progress she meets 3 teens, They were being beaten up when she helped them and patched them up, Those three became attached to her to the point somewhere in the story when one of those teens are throwing a fit in his room his big brother has to call her up and to the surprise of the parents and brother the teen actually listened to protagonist.
It sounds like you're looking for a specific novel. For that, you should change your thread's prefix to "Forgotten Title" - it will attract the right kind of attention to hopefully get someone who remembers it.
