Advise when she pushes you away

I was seeing a girl for about 5 months, first person I've ever met that was an empath like myself. We hit it off. She has a lot of trauma and her parents would not be accepting of her being with a woman. She isn't out of the closet. She completely cut me off and said some hurtful things, I knew that what we shared wasn't a lie so I kept pushing for the truth of why. She admitted that her parents would never accept ya and she couldn't live with that. That she would rather be half happy with them involved then fully happy without them. She said she was trying to push me away and make me hate her so I'd walk away. She has done this before in her previous relationships. I know that she wants to be with me but she won't let me in. She said she's in pain and she is sorry for putting her feelings before mine but it's what she has to do right now. I don't want to give up on her but how can I be there for her if she won't even talk to me? How can someone not be with someone they love because of their parents? I don't understand fully because all of my family is accepting of me. I don't know what to do and I'd really like someone to talk about it too before I drive myself insane
