Good story.

When he wakes next morning another woman tries to have sex with him, he refuses throws her out but the heroine sees them and assumes that the Hero viewed her as a ONS.
He again gets called away on assignment, he's injured and is away months.
Heartbroken the heroine moves in and starts dating.

When they connect the Hero has turned down offers from women during their separation.
The heroine goes for a health check as her ex who she dated during the separation was possibly cheating, so she'd obviously been with others.

Other woman drama and other man drama.
