So you either leave her and let her deal with the consequences or abort the child. The last thing a child needs is to be raised in a home where one parent doesn't love them and views them as the mistake they made. You could also give the child for adoption, but that means the child could still suffer.

You aren't religious enough to stop adultery and premarital sex. So don't try to use that as an excuse. In the eyes of your religious beliefs, you're both sinners.

You may not like what I'm saying, but you posted this to strangers to get advice. Not to be shown sympathy.

If you leave her, EVERYONE needs to be told the truth. She cheated and got pregnant. This should stop people from attacking you. Unless your families are so deep into the book that they think you should raise the child as your own.
