My husband has a very attractive female coworker

I don’t know how to feel and think about the situation. I want to have a positive but realistic approach as to my husband’s new work setup. He is a company doctor and has been recently promoted. His new office and role comes with a deputy/assistant doctor who happens to be a very attractive female. She is young, has a great body, pretty face and great personality. She will be working closely with my husband and actually share an office. They may even be required to go on business trips together.

My husband is a very good and loyal partner but I can’t help but feel a bit anxious and insecure about this. Can you give me tips on how to frame my mind and my heart in this situation? Because I really want to support him with his new role. I dont want to be that nagging and insecure wife but I also dont want to be complacent about this and not have a discussion with husband. If we do talk, whats a good approach I should take?
