Should I feel insecure or is it my anxiety

My husband works at a restaurant all day with a reallllly pretty girl. There are only 5 employees. The owner, 2 cooks, my husband, and this girl. It's a small restaurant. I'm insecure because she is way more attractive than me. I don't really know the Interaction that goes on. She doesn't speak English. She cleans dishes brings food out. Just doesn't talk to the people. I posted the anon because I'm embarrassed for writing so much. He googled how to learn Spanish and other things that would bring up questions.

ETA: he googled "how to find a girlfriend while married AND how to learn Spanish right next to each other.
