I want to test my boyfriend on instagram?

I want to test him with a friend's acc. because he follows and likes a lot of girls and i'm insecure about it. should i find someone and test him? what should i do? i tried to talk a lot of times but he got angry and said he ain't doing anything wrong there, just trying to increase followers 🤦‍♀️
