Wow that sounds terrible... Have you explained that, factually, changing schools isn't going to change your sexuality? What are they expecting? Anyways, i really hope things start to go better for you and him, maybe keep trying to talk to your parents now that it's out of the bag? What's left to worry about now?
Yea they don’t wanna talk about it till I’m legally allowed to leave the house and an adult to make my Own decisions and yea they don’t want me under the influence of LGBT people because they’re “putting things in my head” and manipulating me even tho I’ve felt like this for a long time but I’m doing better now and all these comments made me happy ^^
Tell them to speak with any therapist/health expert and ask if sexuality is something that can be helped. Here is a link to actual professional medical and psychological information regarding this from the American Psychological Association: https://www.apa.org/helpcenter/sexual-orientation.aspx
I regret it now because we got in a lot of trouble for it I won’t go into detail but I’m gay af and when I was dating my boyfriend we were too lovey Dovey and people reported it to the teacher and the whole school knew and the school was pretty chill, my boyfriends parents knew but mine didn’t, my mum found out this year and I was forced to move schools tho but I still love him a lot even if I can’t speak to him or contact him ^^
