boyfriend trouble 🤔

Hi, so my boyfriends best friend has blocked me and my best friend from seeing his stories on snapchat, I know we're blocked for sure as we haven't seen him put a story up for months and my boyfriend says to me "have you seen his snapchat" sometimes, anyway we get along fine me and his best friend so I don't understand why his blocked us. When I confronted him he didn't know what to say and rung my boyfriend to ask him when I was with him but my boyfriend wouldn't answer his call. So they both spoke and then they both said do you want to know why and I said obviously and then they said because they didn't want me to see stories of my boyfriend at betting shops or casinos. 
Does this sound suspicious to anyone? What should I do?
