Romance novel with exes meeting after years of divorce

This is a really old book I read almost 8 years ago, but I am sure it was published long before that. The end of the book was torn so I never got to read the end. I think it's a harlequin book

Plot: the hero is an ex of the heroine from a wealthy family and he used to be poor hence her parents were against their relationship from when they were young,(I am not sure if the hero's family were drycleaners or so but he used to sneak out with the daughter and the dad tried to threaten and buy him off at some point). I think they eventually got married but the parents manipulated her to divorce him and when she filed for divorce her parents blocked him from seeing her or talking to her and tricked them into the divorce really.
They met again years later and she still hates him (doesn't know she was manipulated by her parents) they end up stuck together towards the end for some reason(maybe the divorce wasn't fully complete, I hope I am not mixing up different stories), maybe a job. I am not sure if there was a child involved/miscarriage . Didn't get to see the end
