I’m sorry but I really don’t know how to answer this, you say you’ve never imagined yourself with girl, nor do you think you ever could yet you’re straight up saying that you think you have feelings for a friend? Maybe you think of them as a sister or recently you’ve just bonded in a way you haven’t bonded with a close friend before, don’t ever be afraid to be who you are though - society is so lame atm that everyone judges everyone and so many people give in to that because their sexuality isn’t what’s “suited” to other peoples liking, it’s so stupid! They shouldn’t rule you, you should choose your decisions. Don’t be afraid to be who you are, I can’t say that enough but I can’t help but tell you there’s always consequences:( Butttttt, if you have feelings for this girl and you think she could possibly like you back then you should just take it as you would with a boy I guess.. I’m not really sure, if any of my followers have any better advice then please post it in my ask box :-)
