So I had a conversation with my bf few months ago about being uncomftacle for him liking sexy pics (pics in loungewear etc) especially for girls he know because it felt disrespectful to me. I know not everyone thinks that way but it feel like that for me, and he seemed to understand it and he didn't do it for a while. Recently he like another girls (we both know her) picture in loungewear, I didn't say anything because honestly I just couldn't be bothered having another connection like that again... he has this friend from college (a girl) and she post alooot of pictures like that on her Instagram and videos on snapchat, he wasn't liking them on her Instagram for a while, but recently he started to bring her name up more often, and he use to have our picture together as his profile one but he changed it yesterday and now she posted an loungewear picture on Instagram with a caption "no competition darlin" and he liked it, I don't know if I'm reading too much into it but even if it doesn't mean anything, I feel hurt becoming I told him how it makes me feel especially if it's someone he knows yet he still did it... I'm not sure if i should bring it up to him. I don't follow her on insta but a friend 9f friend does and she told me that my bf liked it.

How do I bring it up, he doesn't know I know and I don't follow her
