Need Help finding a book

I read an interconnected standalone series a while ago, where each book followed a different couple. it was romance books and I remember them being more mature. it was very found family, and all the characters lived in one big house. there was multiple books, and the author even had books written of the main couples kids. I want to say the names of the books were men’s names, but I am not sure. I remember the men being very toxic lol if anyone can help thank you
