My transphobic family Pt1

I have been dating a trans girl for a while now and I love her to bits! We had just gone to prom together and have shared the most lovely weekend at a beach house. Sadly when I got home my mom confronted me, she found out my gf was trans. On the spot my mother forced me to break up with her, so I pretended I did. Honestly it broke me, me and my gfs relationship just started getting more intimate and we had finally had to stop hiding it and then my mom pulls of this stunt. My dad isn't happy with me either yet he said I will always have a home with him (he thinks I'm not dating my gf anymore). I plan on telling him once I'm 18 that I'm still dating a trans girl, just incase I get kicked out. Its gotten to the point were I'm not allowed to go see my friends, and I've been prohibited from crying because my mom said she will punish me if I cry "over a man". She even has my brother watching over me at school incase I do anything. My gf is aware of this and her and her family are supporting me trough out this entire situation. What do you guys think about this whole situation? Do you want me to keep updating?
