So my boyfriend is coming down from new Zealand..I live in australia we are long distance

We haven't seen eachother in a while but anywya we planned to go to this festival with another couple..there's another guy coming so I told me single friend thst she should meet him

Anyway my bf and I wanna go on the train since that's the first time we can see eachother and be alone for a bit..but my friend insists on coming on the train with us?

After the city thing we both will go to seperate places and won't be able to see eachother for maybe more than a week due to complicated situation :/ I've tried explaining to my friend but she just won't

Shes a good friend I just dont think she gets it..

Like when my 3 month old kitten suddenly died I wanted to do something to cheer me up with my bf and a few others..the guy she liked was invited too but the other couple pulled out and so did her crush so her and that other girl got really mad saying it should only be a girl thing and to uninvite him and she ended up calling the whole event off cauee I wouldn't uninvite him

I think she just doesn't get these things
