Looking for a series

Looking for a series I read a while back. It was a historical ma wha/Manga, with nsfw scenes. The main character was a women with long pink/reddish hair, she had issues with her husband (shirt blue/black hair) and they lived separately with her still having to attend events with him. Then here was also another man with blonde hair who either worked for or with either husband and was showing an interest in her??? Please lmk if anyone knows what I’m talking about LMAOO
