@ Bookslover2909 title is: His child, her baby, their family.
Maybe it's not by you, I don't know, I read a book where there were lots of good books recommended with name of the authors too. That's where I found your name. His child, her baby and their family is a book I read a long time a go about a man who has a son with autism (not sure) who divorces his wife because of some reason and moves closer to his parents. At the same time there is a girl who is married to her husband who is really rich. She gets pregnant and they find out something about their baby (don't remember what) so her husband wants her to abort the baby but she says no. So he leaves her and some time later she ends up somewhere around the man from earlier ☝and later they get married. Hope you understood, this was a really cut down version
