Is it worth to finish relationship if my husband checked out a girl's profile on ig because he found her attractive?

It happened few days after marriage, she is a random girl we met at language exam, he will never meet her again and she is not a friend of him. He said she was interesting and attractive and he wasn't going to text her, just wanted to look at her picture out of curiosity. I feel terrible and cannot understand and forgive it. What it can mean and is it a sign he is a cheater?
