I am trying to understand your post, as it's not really written in comprehensible English.
My understanding you have been dating this girl for 3 months. You introduced her to your family pretty much immediately, even though your father was skeptical. But she has never introduced you to her family at all, and won't even tell you where she lives. And now she claims to have some sort of a disease that you cannot help her with and you cannot care for her.
Why are you still dating this woman who is pretty obviously lying to you?
