Okay, this has been happening for a while and it makes me feel as if I am taking part in something that I do not want to be part of. The reason is that when we (her, her boyfriend, me and my sister) are out, she always wants to take pictures. He is in some pictures but she specifically asks him to step out to take a picture with only my sister and me. She gets angry when we do not want to because we feel bad for him (although we never explicitly said it is for that reason and often pretend we are just fed up with taking pictures). She once told us that he would like to be more of a part of our family and that he seemed dejected over the fact that he could not be (because she does not want that). So thinking of that makes me feel worse about that situation. She once said that she has her own reasons for doing so (she was angry). But then did not say what the reason was. I strongly suspect that it is because she wants to have pictures that she can keep in case that they break up. While some part of me can understand this reason (she loves us very much and her family is very important to her), at the same time I feel very bad for him. They have their issues but honestly he seems to be a very good guy... I can understand she wants to have pictures of our memories together that she can keep even after a potential breakup but it is also not fair to him. Personally, I have more arguments but I would like to hear people's neutral opinion on this topic. I am also open to a different perspective if I am to wrapped up in my own biases. The reason being, Iamfed up with this situation. Currently I am planning that next time I will have a serious talk with her to tell her that I do not want to be in any pictures anymore if she continues with that. But I do not know how she will react and I would rather double confirm with others to make sure I am not causing a rift unnecessarily.

Thank you :)
