I have a friend J who is constantly buying and doing the same things I do. You have been friends for 15 years but recently we have started to grow apart. A few years ago I had a friend H who accused me of "copying" her because I posted a picture of my new teacup and she had posted a picture of her holding a completely different cup 3 months earlier. Anyways my friend J is friends with a girl who is 10 and J is 16. Everyone who knows her finds it quite unusual for the large age difference. So are used to tell him J about certain music and YouTubers and she ignored me and told me she didn't like them and now she's obsessed with them. I don't want to be like my old friend who accused me of copying her but I don't know what to do with this situation because we've been friends for 15 years and I just feel like we are growing apart too much and don't have any common interests so I don't know what to do if there's anyone have any advice?
