I Need Support

I could use some help. I am gay and partially out of the closet, mainly at school and I am with a guy I really like. My parents are Christians and I did come out to them as gay and they said they would support no matter what. But now they are saying, “oh god has a wife for you and you know it and god said it is a total abomination towards him.” I am deeply confused because at first they said they will love me no matter what and now they are trying to convert me to a straight male. It doesn’t seem like they really support me telling me god never made me to be with another male. How would we know what god wants if the book was written so long ago and by different languages? How do we know he only made straight people? Isn’t he suppose to be the all loving god? Doesn’t seem like he is the way people keep talking to me about how I am wrong for being gay. Love is love and it has no gender, it has no true form, it has no true definition, it’s all about the connection you feel with someone. What do I do? Just move out if they can’t truly accept it?
