[WWTBC] Romantic suspense where he calls the FMC “Mama”

This is such a long shot because truly, I don’t remember anything about the actual plot of this book, at all haha. But it was part of a series of interconnected stand alones, takes place in a small town, one of the other books was about a MMC cop. This one was not about the cop, it was about some other dude, but he called the FMC Mama as a nickname. She was not a mom, hadn’t ever been and there was no pregnancy trope going on in the book that I remember, he just used mama as a nickname for her and it was literally everything. I feel like the series was more romantic suspense than just straight romance, and there was definitely the whole protection element going on in all the books. I also think one of the books in the series was about trying to help some homeless kid (the cop book, specifically maybe?) but I could absolutely be conflating that with a completely different series cuz I read a lot of romance novels in this sub-genre. If anyone can help, I’d be forever indebted to you because I’ve been trying for months to figure out what this book is and I am dying to reread it.
