Looking for books with widowed FMCS of terrible dead husbands that find hurt/comfort with the new MMC

I looked through older posts, but most are about overcoming the grief for their amazing, beloved dead husband with his best friend/brother/twin.

No. She is free and traumatized (bonus if she even had to kill him herself) but not the typical ‘sassy’^TM FMC.

Specifically looking for her overcoming the past abuse of the dead husband.

Don’t particularly like Mafia or MC, but all else goes ( including Reverse Harem, F/F, historical, fantasy, etc)

Thanks!!!
