Should I Be Worried

So my bfs Italian been together 3 years. Him and I both follow other ppl and ppl we don’t even know on Instagram. He follows this Italian girl who’s rlly pretty and he likes all of her pics. Today I was on his phone and saw in his Instagram search history she was there which means he wanted to look at her. I’m worried about it because she’s Italian like him and rlly attractive. Plus hes said many times he wishes I was Italian like him. I told him to unfollow her cause now I’m uncomfortable and he was like why? But did it after. Advice?
