Why does my best circle of friends like to send photos of her and her aunt and friends in their 50 s, and never send photos of us?

He's probably just trying to protect you

I think there is still a big age gap between your girlfriends. In fact, he has a wide range of friends. Maybe those people are his family, or some relatives he is familiar with. I think this may be because your family knows, but your existence may not be understood by others.

So sometimes he sends these photos because he thinks everyone in his circle of friends knows them, so others won't ask too many questions when he sends them. If he sends you a photo, others may be confused, maybe he just wants to protect you and doesn't want your privacy or other things to be known.

Actually, I think the relationship between you is still good. After all, you are best friends, so I think you will always get along under any circumstances. You don't have to make friends to have a good relationship with you, because you have to know that you are both adults, and I think you should learn another way to get along. Maybe it's because he sent photos of others, and then you got jealous, so you're so sad, but I think it's actually nothing, because many people around me are like this. Even people of the same age, he will send photos of others, and he won't send photos of you, so I think these are normal phenomena. Learn to take a good look at this kind of thing, without thinking in your head.

So sometimes it is necessary to understand this relationship. Don't always take such things too seriously, because as long as you are happy together, better communication is possible.

My friend, his friends are quite many, so I don't care whose photos he sends, because he has the right, so sometimes it's not too selfish, because everyone has the right to know more people or send photos with his family.
