ginjay fanconcert, not sure whether to go

hiii. so recently got into gl and I really wanted to go for ginjay’s fan concert in sg. buuut when I told my bestie she said nooooo because why do I wanna waste money just to meet them. she also isn’t a fan on my fangirling over ginny, she gets very annoyed and says I’m idolizing her. I’m still tempted to go bc I rly like her so much. but I also don’t wanna end up fighting w my bestie over this
