So basically my boyfriend has two other instagram that he doesn't use but I saw that he is logged into both apart from the instagram he already uses and when I asked he said he follows rappers etc on them. I then without him knowing logged into both and on one of the account he had searched a girl which had followed in his original account but I removed the request. The girl has a very revealing picture on her instagram display picture and he went on another account to basically check her out. What should I do?
