LOL!! That title doesn’t say much (this could be SO many books), but all the true detail in the question could be deemed as spoilers, so I spoiler-alerted on them and left that title generic. 
Bewaji asks:
Hey Maryse, I know your wonderful readers will help me out about a book I read a long time ago. It stayed with me and I want to read it again and for the life of me, I can’t find it on my Kindle.
*The H and h got married young (maybe out of High School), had two kids, stuff happened and they divorced.
Years later, H lost his brother, so h went to commensurate.

I think H had a fiancée or so, they kind of got together, her daughter did not like that, made some trouble etc etc,

but they got back together anyways. .
Thanks in advance.
Anyone have a guess?

Maryse: YAY!!! Glad you for it Bewaji!!! 
I am happily addicted to reading but I need to expend my book energy (especially when one puts me in an emotional frenzy - SO fun!). So, I release my feelings about the stories, by writing them down here. It's my book therapy.
