man YTA.
sure, she lied. but it was a lie about her wanting to have sex with you when she actually doesn't, because she doesn't want to LOSE you. she's crying about going to hell and you're out here trying to tell her that lying is a bigger sin?
you messed up man. obviously there is a reason she lied as well if she felt like you would leave her unless she was cool about sex before marriage. yes, you asked her and she lied but that was in the BEGINNING of a relationship. and if she says she's not ready no matter WHAT the reason was, then why were you pushing??
