What would you do?

I'm trying to understand if I'm crazy or what I should be doing with this situation. My bf plays this video game and has a kik chat for it and his friend he hangs with here in town also plays and posted in the game kik chat naked pics of his wife and their three way relationship girlfriend and I feel like that is totally disrespectful to myself in doing that and my bf doesn't agree. Like how would you guys feel or do with this type of situation?
