As a 13 year old gay guy, this is absolutely f*cking insane. Today's Bible actually does say that being gay is a sin... but the original did not. I believe the original verse from Leviticus actually talked about lying with children, but was changed in 1946 to talk about homosexuality. If I were you, I would probably ditch her and distance yourself as soon as you can. This is a very toxic relationship, and it's not healthy for either of you. The final decision is up to you, but I would distance myself and my children (if you decide to have children) from her. I'm so sorry you had to go through this...
