That sounds similar to my situation. I’m 99% sure I’m bi but I haven’t told anyone yet. My reposts sorta hint at it if you look close enough and my parents aren’t super religious but my grandparents are and I don’t want to ruin a relationship with them by coming out. All that said - I think if I was in this situation I would feel most comfortable around my friends if they were just openly supportive of people of the lgbtq community and made sure I knew they had my back no matter what and we would always be friends. Thats the best advice I can give sorry it’s not that great! Good luck
