Husband likes to dancing with me, to see if women flirt with him

My husband of 25 years just recently informed me that when we go dancing, he doesn’t particularly loves to dance with me but he likes to see if other women check him out.
To hear this, broke my heart. I honestly thought that it was a bonding activity for him as well. Dancing with him made me feel loved and desired.
Now, I do not feel like going dancing with my husband ever again. Which is a shame since we are both ok dancers.
Anyone has any advice or a similar experience?
