Thanks to everyone who left helpful comments! A few of you really helped me sort this out.

My boss never responded to the picture. So last night, I texted him to explain what happened. I meant to take a picture for my husband’s eyes only. Sending it to him was a complete accident because of the spelling of both names. I’ve since changed my husband’s contact to "Hubby" 💍 to avoid any more mistakes. He didn’t respond to that either!

He was in the office today and acknowledged me, but didn’t mention the text or the photo. I might just be overthinking this, but I was treated very differently by his wife.

She is part owner of the company and is usually never in the office, maybe two days a month at most. She was there today before me and talked to me throughout the whole day, which added to my stress. She asked a lot about my husband, who she met once maybe two years ago. She also asked a lot about what I do outside of work, which felt random!

Again, I could be overreacting, but now I’m worried she might have seen the photo. I don’t know what to do, but it could all just be in my head, and I might be overthinking it. 🙃
