DD is 24, ahead lives in New Zealand with her boyfriend of over a year. Over the last few years DD has become an active user/poster on TikTok. Initially it started when she was on her gap year and she would just post little clips edited together, or her playing games/dancing with the people they were with. All innocent. She has continued and now the stuff she posts is basically one of 4 things, her boyfriend playing guitar while she sings, she/her friends/her boyfriend doing little trending dances, little clips from dates/nights out with friends etc edited together or her doing some of her sports. The only reason I ever go on the app is to see what she's posted, it's nice seeing her happy. DH also has the app and only uses it to see DDs posts but he complains constantly that it's pathetic, pointless, embarrassing etc. I've suggested if he doesn't like it, he delete the app but no no he continues to watch everyone and complain about it. She doesn't have lots of followers or anything she does it as she enjoys it and DH tells her every time we talk how much he hates it, she just ignores him saying he hates it or says something like "well I like it".
AIBU to think that there is nothing wrong with what she's doing and his constant complaints are uncalled for?
