Lesbian (me)

Hi, I am.Madison I am 13 and the only child in my family. But there is one thing my family does not know about me. That is I am a Lesbian I'm happy being one too. But I am dating a guy so they don't find out that I am one. But he does not know I am a Lesbian too. And it's getting harder to come out. I am also poly and its weird for me too. But when I think out loud about this it is wrong. I know God loves me and we are all perfect for him but it's hard to think thats true. Because I get comments on my Instagram or DMs saying it is just a "phase" I dont know what to do anymore. I need help...
