“Insecure”?

Just wondering if anybody else feels a little sting in their heart when their partner consistently likes half naked pics of women you know and are familiar w/ you. Am I just insecure? Controlling? I don’t want to feel the way I do about things like that but it almost seems involuntary. My stomach drops to my feet instantly when I see his name always under a females photos. Makes me feel like he has a preference because even though he’s w/ me, they don’t look like me... and I’m always so considerate. I could see a half decent guy and keep scrolling w/ no acknowledgement but it seems like he always has to make his presence known. Idk, any advice helps. I take criticism well. Thanks
