Girl added my husband as “close friends” on insta

She is a friend of both of us we know her entire family and her brother is good friends with my husband has even worked for him before. She recently started becoming a insta-gym girl where she posts her work outs. The difference is she only posts them under the “close-friends” groups and my husband is added to it.

For some reason I think that made it worse? If it was public for everyone to see who cares really there’s so many people doing that. I just think it’s weird that she specifically made a group under close friends to post these where she’s half naked squatting and added him to the group.

I don’t wanna seem insecure I’m 30 yrs old for fucks sake but isn’t this bizarre? There’s no way in hell I’m messaging her about it because that’s just silly but what would you do in this situation?
