Looking for a loving wives story

[JuneDream]

Hello, I’m looking for a story I read years ago. It’s starts off the with MC with his then gf or wife and then they break up due to her cheating. He then marries her best friend and they have some kids, at which point the best friend dies and leaves him alone with the kids. The ex then comes back and helps become the live in mom and nanny and they reconcile in the end
