Solved: Cheating husband, hero is co-worker, new client? Takes her home sick

She catches her husband cheating or suspects and confronts him. Hero is maybe new boss or co-worker,  new client, something like that.  I want to say they meet over a display table of some kind. He's interested from the get go and I think she is too, but holds back at least I think.  I think he doesn't know she's married right away, but can't remember if she's aware of this or not.  Scene I remember is that he takes her home sick or injured (concussion?) and stays with her because her husband is mia.  She is on her living room couch.  Husband  finally shows up and is miffed he stayed, even though she needed someone.  She moves out and invites hero for dinner as a friend. Zero shows up at her place, he wants her back but she ain't having it.
