Book recommendations where mmc bodyguards fmc who is also her ex

Guys recently dreamed up this romance scenario in my sleep and now I’m desperate to find books with a similar vibe.
The FMC comes from a wealthy, influential family and breaks up with the MMC because her family doesn’t approve of him. They think he’s not good enough for her so she sacrifices the relationship.
Fast forward about a decade. The FMC is now married to a wealthy, famous man (maybe a politician) whom her family chose for her. She doesnt have a happy marriage and because her husband is such a public figure there are threats against her. Despite her protests, he insists on hiring a bodyguard.
The bodyguard turns out to be the MMC.
In the years since they broke up, he’s become incredibly successful and is now one of the most in demand bodyguards. They’re forced into close proximity there’s all this unresolved history and plenty of angst.
Does anyone know of books with a remotely similar premise? It doesn’t have to match every detail, but I’d love second-chance romance with forced proximity a bodyguard MMC and lots of emotional tension.
