Wife is attracted to my best friend

Hi. My (M32) wife (F27) has been acting awkward and avoiding certain people during our gatherings for the holidays. Whether firends or family.

So I asked her to be open with me and tell (we have honesty policy). She said that she is attracted to my best friend and think he’s handsome and reminds her of old hollywood stars.
She also mentioned that she was attracted to my cousin who’s in college (21 or 22) as his energy reminds her of college and his fun personality and youthfulness take her back to that time.

I’m glad that we’re open with eachother, but I don’t feel ok about it and wish I didn’t ask to be honest.
