Can't remember the name of the book with guy nicknamed Sublime [s]

I read this 4-5 years ago and I still can't remember the title.
The male protagonist was (I think) a retired boxer who was given the nickname Sublime. And before he met the female protagonist, I believe he found out his girlfriend was cheating on him cause he found a picture.
And the female protagonist was having trouble with an ex-boyfriend who was stalking her. And the guy end's up falling in love with her.

Sorry if that's not enough information, but I've been trying to find the title for a while now

It's one of Lori Foster's series about mixed martial artists and the women they get involved with. It's the second book and is called Simon Says I believe. If not that one, it's one of the others in her SBC Fighters series, but I'm pretty sure that that's the correct title for your book.
